The method of evaluating the effectiveness of firing a combat remote-controlled module located on a moving object is as follows. To assess the firing efficiency of a combat remotely controlled module (BDM) 1, it is placed on a moving object (PO) 2. The firing efficiency indicator is the probability (frequency) of hitting the target and the time it takes the crew to prepare and produce one turn. The principle of determining performance indicators is to determine the probability (frequency) of hitting a target of at least one bullet from a queue of 10 bullets and determining the time taken by the crew to prepare and produce one burst when firing from the BDMUM 1 weapon system mounted on PO 2 , on the move and from a place on motionless and moving targets at real ranges through day and night channels of sighting systems from the gunners ’place in normal modes.

A positive result when shooting is taken to be the defeat of the target. The criterion for the defeat is that at least one bullet from the line of 10 bullets hits the target. The frequency of hitting target P is calculated by the formula

where n is the number of defeats of the target determined during the firing;

N is the number of queues produced.

3. At the third stage, the confidence probability of hitting target y is calculated by the formula

where D _max - the maximum value of the range to the target in accordance with regulatory documents;

V _max - the maximum speed of the test object for firing on the move in accordance with regulatory documents;

T _P - the time of preparation and production of the queue in accordance with regulatory documents.

The minimum value of the distance to the target from the line of fire (POO) 3 ... 5 is calculated by the formula

n _Ф is the brightness of the background, averaged over the area of the background bounded by a rectangle with dimensions 2 times the largest height and width of the target, and superimposed by its center on the center of the target.

The meteorological visibility range is calculated by the formula

When evaluating the effectiveness of firing BDUM 1, placed on PO 2, firing is carried out on the move and from a place on a fixed 11 and 12 targets making a flanking movement. The speed of movement of PO 2 with BDUM 1 and moving target 12 in a medium-rugged terrain during firing is 25-30 km / h. Goals 11 and 12 should be fully projected onto the background of the terrain, not exceeding the horizon line. The route should provide direct visibility of the target without screening it on the ground. The measurement of the distance to the target is carried out before each queue. The maximum possible number of range measurements for firing at one target on the move is calculated by the formula (11). Meteorological shields 8 and 10 for determining the transmittance of the atmosphere consist of 2 equal squares, painted in white (ρ ₁ ) 7 and black (ρ ₂ ) 9 paint. Reflection coefficient of the light flux of paint: ρ ₁ ≥0.85, ρ ₂ ≈0.5ρ ₁ . The size of the shields is determined on the basis of the following conditions: the shields, regardless of their installation range, should occupy approximately the same area in the flat field of view of the observing device, taking into account the change in the multiplicity of the vision of the latter. When using 2 shields, one of them is installed directly at the starting line of the test director, the second - in the target area.

Before testing:

- preparation for firing at PO 2 is made, arms are adjusted, posts for measuring parameters of external conditions and targets are deployed, a video camera is installed, schemes of the target situation are developed, in which the sequence of firing, range, initial line (IR) 13, ROO 3 ... 5, RPO 6 are determined set targets;

- Software 2 is installed on IR 13;

- at a distance of 20-30 m from IR 13, a stationary laser range finder (LD) 14 is installed;

- measurements of external conditions are carried out, meteorological data are calculated according to formulas (14) ... (16).

Shooting from a place on three motionless targets spaced along the front:

- in accordance with the scheme of the target situation, the quantity and type of ammunition, the order of firing targets, the number of bursts when completing a task are determined;

- after receiving a command to perform an exercise, BDUM 1 is brought into a combat position, the video camera is turned on;

- PO 2 moves from IR13 to ROO 3;

- when ROO 3 is reached, a command is issued to open fire on the first target, the stopwatch is turned on and off at the time of the queue;

- on a command to fire, the range to the target is measured, the value of which is compared with a previously known range of values, if the values do not match, the measurement is repeated;

- at the same time, the shooting results are recorded (hit, miss).

Shooting from a place on one moving target, shooting on the move at three stationary targets spaced along the front and in depth, firing on the move at one moving target are carried out similarly in accordance with certain patterns of the target situation.

The probability of hit (defeat) R _N software method in the environment of MathCad. The value of confidence probability is taken equal to y = 0.8 (the risks of the customer and developer are β = α = 0.1).

When processing the results, the video is analyzed for accuracy of aiming at the target, and in the absence of instrumental errors, queues that have gross aiming errors are excluded. If there is a high-quality sound recording of the video camera, the calculation of the preparation and production time of each queue is performed according to the formula (7), the preparation and production time according to the results of all the queues - according to the formula (8), the speed of movement of PO 2 during the production of each queue - according to the formula (12), average speeds - according to the formula (13).
