Description

The invention relates to weapons, in particular to systems for the integrated use of reconnaissance, automated control and fire destruction.

A known method of hitting objects (see, for example, Military Parade. - M .: Military Publishing House, 2005, February, pp. 10-13), including: search, detection, recognition, determination of the coordinates of targets; clarification of coordinates of previously identified objects, opening of newly appeared objects; transfer of intelligence to the automated control system; salvo launch of guided ammunition on identified targets; selection of the target on board each individual guided munition; simultaneous destruction of selected objects by all guided munitions.

The disadvantages of this method of destruction are the irrational consumption of guided ammunition when a group of enemy targets is hit, associated with the possible guidance of several guided ammunition on the same target, while other objects remain unshooted, and guided guided ammunition on an already hit object.

The technical result, the achievement of which the present invention is directed, is a more rational consumption of guided munitions, by eliminating the possibility of pointing several guided munitions on the same target, while others remain unshooted, and eliminating the possibility of aiming guided munitions on an already hit an object.

объекта.The technical result is achieved by the fact that in the known method of high-precision destruction, which consists in searching, detecting, recognizing and determining the coordinates of the objects to be attacked, clarifying the coordinates of previously detected objects and opening the newly appeared objects, transmitting intelligence to the automated control system, launching guided ammunition by means of fire destruction, sequential launch of guided ammunition with a time delay t _ass relative to each other t _ass = t ₁ + t ₂ + t ₃ + t _{max, m} , where t ₁ - time is required nd for assessing the degree of damage to an object by the previous guided munition, t ₂ is the time required to form and transmit a command to the guided munition to direct it to a separate group object, t ₃ is the time necessary to work out the command to switch to pointing to a separate group object, t _{max, m} - maximum guidance time of guided ammunition on the mth

the group object after the turn of L ₄ , the defeat of objects is carried out sequentially according to the results of the control of the degree of damage n-m (

; N is the number of guided munitions) guided munition m-th (

; M - the number of targets) of the target; pointing n + b + 1st (

, b - the first controlled munition after the n-th, which hit the m-th object,

b = 0,) on m + 1st

the object of defeat is carried out only after the defeat of the m-th

object.

The essence of the invention is to defeat a group of objects by sequentially launching guided ammunition, aiming them at individual objects in the group when approaching them, controlling the degree of destruction of objects by guided ammunition, while the sequence of defeating objects of the group is formed in accordance with their importance, and switching to the defeat of the next important defeat of the object of the group is carried out only after the defeat of the previous one, etc. before the defeat of all objects of the group.

Figure 1 presents a simplified diagram of the implementation of the proposed method (option).

Figure 2 presents the algorithm for sequential destruction of objects.

Figure 3 shows the direction of launch of guided ammunition.

Figure 4 presents the principle of the search for the object of destruction on board the guided munition.

Figure 1 marked:

1 - intelligence system;

2 - automated control system (ACS);

3 - means (a) fire destruction;

4 - guided munition (s).

The reconnaissance system (1) (see, for example, Military Parade. - M.: Military Publishing House, 2005, February, pp. 10-11) searches for, detects, recognizes, determines the coordinates of targets, determines the coordinates of previously identified objects, opening of newly appeared objects, and transmits data on the detected objects to the automated control system (2), where the required number of guided munitions, N, is determined to destroy the entire identified group of M objects with the required probability. Before launching guided ammunition in their on-board digital computers (BCMs), a database of reconnaissance features of the targets is created. Also, before the launch of guided ammunition, based on the duration of the cycles of assessing the degree of destruction of the object by the previous ammunition and guiding the guided ammunition on the affected objects, the following boundaries are determined (figure 2):

1) line L ₁ - the line for assessing the degree of damage to an object by the previous guided munition;

2) line L ₂ - the line of formation and transfer of the command to the board of the guided munition for its guidance on a separate object of the group;

3) boundary L ₃ - the boundary of the development team transition to guidance on a separate object of the group;

4) line L ₄ - the line of transition to guidance on a separate object of the group.

Next, the weapon (a) fire destruction performs a sequential launch of guided ammunition in the direction of the geometric center of the location of the objects of destruction on the ground (figure 3). This center is determined by sequential averaging of the coordinates of the group objects. The launch of guided ammunition is carried out with a time delay t _ass relative to each other. The calculation of the time t _{ass is} made according to the formula

объект группы после рубежа L₄, т.е. m-й

объект группы, наведение на который управляемых боеприпасов после рубежа L₄ требует максимального времени.where t ₁ is the time required to assess the degree of damage to the object by the previous guided munition, t ₂ is the time required to form and transmit a command to the guided munition to aim it at a separate object of the group, t ₃ is the time required to work out the transition command to pointing to a separate object of the group, t _{max, m} - the maximum time of guiding guided ammunition on the m-th

the group object after the boundary L ₄ , i.e. mth

the group object, the guidance of which guided ammunition after the line L ₄ requires maximum time.

Due to the sequential launch of guided ammunition, the average distance between them in flight is

- средняя скорость полета управляемых боеприпасов. Рубеж L₄ определяется расстоянием от группы поражаемых объектов, с которого можно наводить управляемые боеприпасы на любой из объектов группы. Остальные рубежи откладываются от рубежа в сторону средства огневого поражения и расстояния между ними соответственно равны (фиг.2):Where

- the average flight speed of guided ammunition. The boundary L _{4 is} determined by the distance from the group of affected objects, from which guided ammunition can be aimed at any of the objects of the group. The remaining boundaries are delayed from the boundary towards the means of fire destruction and the distances between them are respectively equal (figure 2):

системой разведки производится контроль степени поражения первого объекта первым управляемым боеприпасом. Если первый объект не уничтожен, то управляемый боеприпас, пущенный вторым, наводится на первый объект поражения, в противном случае - на второй (m=2) объект поражения. Для наведения второго управляемого боеприпаса на выбранный объект поражения на его борт в течение времени, не превышающем

передается команда, формируемая АСУ, информационная часть которой включает в себя координаты поражаемого объекта (x_m, y_m, z_m) и указание на его разведывательные признаки в базе данных БЦВМ. Далее, после приема и обработки команды на наведение на выбранный объект поражения и определения его разведывательных признаков в базе данных БЦВМ, между рубежами L₃ и L₄ бортовыми средствами разведки производится его поиск в области пространства, ограниченного объемом, геометрический центр которого (фиг.4.) задан x_m, y_m, z_m, а размеры х_m±Δх, у_m±Δу, z_m±Δz, где Δх, Δу, Δz определяются законом распределения ошибок целеуказания (см., например, Бакут Б.А. и др. Вопросы статистической теории радиолокации, 1963, стр.174), время поиска не более

До рубежа L₄ бортовые средства должны обнаружить выбранный для поражения объект и перейти на его сопровождение. Не позднее преодоления рубежа L₄ второй управляемый боеприпас должен перейти на наведение на выбранный объект поражения. Поражение оставшихся объектов группы осуществляется аналогичным образом.The defeat of objects is carried out sequentially in accordance with their importance, determined by the degree of their influence on the functioning of enemy systems, of which they are elements in general (see, for example, Air attack tools of foreign countries: development programs for precision weapons. / Under the editorship of B. Cheltsov. ., Yagolnikova S.V., Ministry of Defense of the Russian Federation 2 Central Research Institute, 2003, p. 15). Suppose that in accordance with the importance of the defeat and the launch sequence of guided munitions, they are assigned numbers (i.e., the number of the most important from the point of view of defeat is unity, etc., the number of guided ammunition fired first is unity, etc.). Guided ammunition fired first (n = 1), strike the first object of destruction (m = 1). The strike of the first (n = 1) guided munition against the first object of destruction (m = 1) should occur before the second (n = 2) guided munition arrives at line L ₁ . Further for a time not exceeding

the intelligence system monitors the degree of damage to the first object by the first guided munition. If the first object is not destroyed, then the guided munition fired by the second is aimed at the first target, otherwise, at the second (m = 2) target. To aim the second guided munition at the selected target on its side for a time not exceeding

a command is formed, formed by the ACS, the information part of which includes the coordinates of the target (x _m , y _m , z _m ) and an indication of its reconnaissance features in the digital computer database. Further, after receiving and processing the command to aim at the selected target and determine its reconnaissance signs in the digital computer database, between the lines L ₃ and L _{4 by} airborne reconnaissance equipment, it is searched in the area of space limited by the volume, the geometric center of which (Fig. 4 .) given x _m , y _m , z _m , and dimensions x _m ± Δx, y _m ± Δy, z _m ± Δz, where Δx, Δy, Δz are determined by the distribution law of target designation errors (see, for example, Bakut B.A. . and others. Questions of the statistical theory of radar, 1963, p. 174), search time no more

Until the turn of L _4, airborne vehicles must detect the object selected for destruction and switch to its escort. Not later than overcoming line L _{4, the} second guided munition must go over to aim at the selected target. The defeat of the remaining objects of the group is carried out in a similar way.

объекта поражения; наведение n+b+1-го (

b - первый по счету управляемый боеприпас после n-го, поразивший m-й объект,

) на m+1-й

объект поражения осуществляют только после поражения w-го

объекта.In general, the order of destruction of objects can be represented as follows. Intelligence system (1) controls the degree of damage n-m

m-guided ammunition

object of defeat; pointing n + b + 1st (

b - the first controlled munition after the n-th, which hit the m-th object,

) on m + 1st

the object of defeat is carried out only after the defeat of the w-th

object.

We will evaluate the proposed method of defeat in comparison with the defeat method adopted as a prototype. As an indicator of the effectiveness of the application of the method of destruction, we take P (K / M, N) - the probability of destruction of at least K - objects (0≤K≤M) from M - objects when striking with N - guided ammunition. Define the conditions for solving the problem of evaluating the effectiveness of methods of destruction:

- all affected objects are considered pre-identified;

- during the striking, guided ammunition does not affect the functioning of each other;

- affected objects have identical unmasking features for reconnaissance systems;

- the probability of destruction of any object of destruction by any guided munition is the same and equal to p;

- the number of guided munitions is greater than the targets of destruction (N> M).

To find the probabilities P (K / M, N), we initially determine the probabilities P '[k / M, N) (the probabilities of hitting exactly k - objects (0≤k≤M) from M - objects, when struck by N - guided ammunition) .

For the method of destruction adopted for the prototype, due to the fact that the choice of the target is made on board each individual guided munition, any of the N - guided munitions can be aimed at any of the M - targets. For such a case, the number of all possible distributions of (7) N - guided ammunition over M - targets is equal to the number of deployments with repetitions (see, for example, Kuzmin O.V. Enumeration combinatorics. M: publishing house of Drofa, 2005, p. .41-42)

(I - количество всевозможных распределений N - управляемых боеприпасов по М - объектам)We introduce the hypotheses H _i , which consist in the distribution of N - guided ammunition over M - objects, where

(I - the number of all possible distributions of N - guided ammunition for M - objects)

гипотезе на m-й

объект поражения. При этом при гипотезе Н_i where n _{i, m} is the number of guided projectiles that fell at the i-th

hypothesis on the mth

object of defeat. Thus under the hypothesis H _i

Since the above complete group of events (5) - distributions of N - guided munitions over M - objects includes incompatible events (at the same time there can be only one variant of the distribution of N - guided munitions over M - objects) and one distribution of guided ammunition is independent of another, then the probability of damage to exactly k - objects under the hypothesis Н _i (P (K / H _i )) is equal to the coefficient at z ^k in the expansion in powers of the z - generating function (see, for example, Ventzel E.S., Ovcharov L.A. Tasks and exercises in probability theory. M.: Publishing house of Academ I, 2004, p.70, 83):

- вероятность поражения m-го объекта при наведении на него n_m - управляемых боеприпасов,

- вероятность непоражения m-го объекта при наведении на него n_m - управляемых боеприпасов.Where

- the probability of destruction of the m-th object when you hover on it n _m - guided ammunition,

- the probability of non-defeat of the m-th object when n _m -guided munitions are hovering over it.

- числа вариантов распределения N - управляемых боеприпасов по М - объектам, удовлетворяющих условию данной гипотезы к I - числу всевозможных вариантов распределения N - управляемых боеприпасов по М - объектам.The probability of the hypothesis H _i is equal to

- the number of options for the distribution of N - guided ammunition over M - objects that satisfy the hypothesis of this hypothesis to I - the number of all possible options for the distribution of N - guided ammunition over M - objects.

- количество вариантов распределения N - управляемых боеприпасов по М - объектам поражения, благоприятных гипотезе Н_i, подсчитаем следующим образом. Число способов, какими можно выбрать из N - управляемых боеприпасов n_i,1 - управляемых боеприпасов, распределенных на первый объект поражения, равно

(число сочетаний); число способов, какими можно из оставшихся N-n_i,1 управляемых боеприпасов выбрать n_i,2 - управляемых боеприпасов, равно

и т.д.; число способов какими можно из N-(n_i,1+n_i,2+...+n_i,M-1)=n_i,M управляемых боеприпасов выбрать n_i,M управляемых боеприпасов, равно

Для нахождения числа вариантов распределений N - управляемых боеприпасов по М - объектам поражения соответствующих гипотезе Н_i все эти числа нужно перемножить (т.к. при всех вариантах выбора управляемых боеприпасов, распределенных на первый объект

возможны все варианты выбора управляемых боеприпасов, распределенных на второй объект

и т.д.)Number

- the number of options for the distribution of N - guided ammunition over M - objects of destruction favorable to the hypothesis N _i , we calculate as follows. The number of ways that you can choose from N - guided ammunition n _{i, 1} - guided ammunition distributed to the first object of destruction is

(number of combinations); the number of ways in which of the remaining Nn _{i, 1} guided ammunition to select n _{i, 2} - guided ammunition is

etc.; the number of ways in which from N- (n _{i, 1} + n _{i, 2} + ... + n _{i, M-1} ) = n _{i, M} guided munitions to choose n _{i, M} guided ammunition is

To find the number of distribution options for N - guided munitions over M - destruction objects corresponding to hypothesis N _i, all these numbers need to be multiplied (because for all the choices of guided munitions distributed on the first object

all possible choices of guided munitions distributed to the second object are possible

etc.)

Then the probability of the hypothesis P (H _i ):

Knowing the probabilities of the hypotheses P (H _i ) (10) and the likelihood of hitting exactly K - objects from M - objects when struck by N - guided ammunition (the coefficients of z ^k in the expansion in powers of the z - generating function (7)), the full probability formula, we find the probability of destruction of exactly k - objects from M - objects when striking with N - guided ammunition

Thus, we obtained a formula for finding the probability of destruction of exactly k - objects from M - objects when striking with N - guided ammunition (M <N) for the method of destruction adopted as a prototype

Knowing the probabilities P '(k / M, N) of the defeat of exactly k - objects from M - objects when striking with N - guided ammunition (12), one can find P (K / M, N) - the probability of hitting at least K - objects ( 0≤K≤M) from M - objects when striking N - guided ammunition. For this, it is necessary to add the probabilities P '(k / M, N) for

где J - количество вариантов события А). Например, пусть первый вариант события А₁ заключается в поражении k - объектов (k<M) из М - объектов поражения, при нанесении удара N - управляемыми боеприпасами первыми пущенными k - управляемыми боеприпасами; соответственно последующие N-k пущенные управляемые боеприпасы не поразили объекты. Вероятность такого события Р(A_i) равнаFor the proposed method of defeat, we have the following. Let event A consist in the fact that exactly k - objects (k <M) from M - targets are affected, when struck by N - guided ammunition when implementing the proposed method of destruction. Event A splits into a series of options A _j , (

where J is the number of variants of event A). For example, let the first variant of event A ₁ consist in the defeat of k - objects (k <M) from M - objects of destruction, when struck by N - guided munitions, the first fired k - guided munitions; accordingly, subsequent Nk fired guided munitions did not hit targets. The probability of such an event P (A _i ) is equal to

where q = 1-p is the probability of failure of one object with one shell.

The number of options A _{j of} event A is equal to the number of ways in which k can be selected from the N-shells that hit the objects. This is the number of combinations (see, for example, Kuzmin O.V. Enumeration combinatorics. - M.: Publishing house of Drofa, 2005, p. 26)

To find the probability of the event P (A), it is necessary to add the probabilities of its variants P (A _i ) (the rule of addition of probabilities) or multiply P (A _j ) by J

or

The resulting formula expresses a binomial probability distribution

When K = M

из М - объектов, при нанесении удара N - управляемыми боеприпасами, при применении предлагаемого способа поражения находится аналогично (13).Probability P (K / M, N) of damage not less than K - objects

of M - objects, when striking with N - guided ammunition, when applying the proposed method of destruction is similar to (13).

Figure 5 presents the probabilities of the defeat of 3 objects when striking with 4 guided munitions, calculated by the above methodology for assessing effectiveness. The defeat method adopted for the prototype corresponds to the graph drawn by the dashed line, the proposed method of defeat is solid. A significant increase in the probability of damage to all 3 objects when applying the proposed method of destruction is obvious. This is due to the fact that in the proposed method of destruction eliminates the guidance of several guided ammunition on the same object, while others remain unshooted. This also eliminates the guidance of guided ammunition on already affected objects.

Thus, the proposed method of destruction can significantly reduce the consumption of guided ammunition in case of defeat of a group of objects with the required probability.
