A device for modeling a reconnaissance catalog of heterogeneous mobile objects as follows.

, содержащий математические ожидания длины M[D_j] и ширины M[S_j] для каждого из m типов подвижных объектов. Указанные значения перед началом работы устройства загружаются в регистр 5 сдвига в виде массива чисел.It is assumed that there is a vector $${\overline{X}}_{\mathrm{about}b}=\left(\left(X_{\mathrm{one}},Y_{\mathrm{one}},D_{\mathrm{one}},S_{\mathrm{one}},\Delta l_{\mathrm{one}}\right),\left(X_2,Y_2,D_2,S_2,\Delta l_2\right)...\left(X_n,Y_n,D_n,S_n,\Delta l_n\right)\right)$$

containing the geographical coordinates of the location (latitude X, longitude Y), width S, length D, and the maximum linear resolution on a background Δl n of moving objects, in addition, the standard deviations of the measurement error of the width σ _S and length σ _D , as well as the vector $${\overline{Y}}_t=\left(\left(M\left[D_{\mathrm{one}}\right],M\left[S_2\right]\right),\left(M\left[D_{\mathrm{one}}\right],M\left[S_2\right]\right)...\left(M\left[D_m\right],M\left[S_m\right]\right)\right)$$

containing mathematical expectations of length M [D _j ] and width M [S _j ] for each of m types of moving objects. The indicated values before starting the operation of the device are loaded into the shift register 5 as an array of numbers.

When the device is started from an external source, not shown in the drawing, the clock generator 1 generates pulses to the input of the random number sensor 2, in which uniformly distributed numbers ζ are generated in the range from 0 to 1, which are sequentially transmitted to the input of the comparison unit 4.

It is known that the probability of detecting a moving object P _about against a certain background depends on the size ratio (width, length) of the detected object and the maximum linear resolution in the image of the moving object [2]. In block 3 of the calculation of the probability of detection of a moving object, the calculation of the probability of detection of the i-th moving object.

In block 4, the values of ζ and P _obi , are compared. If ζ <P _obi , then it is considered that the ith moving object is detected. The fulfillment of this condition corresponds to the level of the logical unit at the output of block 4 comparison.

At the same time, in the block 10 for calculating the coordinates of the moving object [2], the possible coordinates of the location of the detected moving object (X _pi , Y _pi ) are determined and transferred to the register 11, where they are written to it, thereby creating the first part of the record of the reconnaissance catalog.

At the same time, the possible results of measuring the length D _i ^* and the width S _i ^{* of the} detected moving object in block 6 for calculating the size of the moving object are determined by the formulas:

$$D_i^{*}=D_i+{\nu }_D,(\mathrm{one})$$

$$S_i^{*}=S_i+{\nu }_S,(2)$$

where ν _D = N [0, σ _D ] and ν _S = N [0, σ _S ] are random variables distributed according to the normal distribution law with mathematical expectations equal to 0 and standard deviations σ _D and σ _S, respectively.

The possible results of measuring the length D _i ^* and the width S _i ^{* of the} detected moving object are transmitted to block 8 for calculating the squares of deviations in the dimensions of the moving object. At the same time, according to the clock signal from the generator 7 clock pulses, this block receives mathematical expectation from the register 5 of length M [D _j ] and width M [S _j ] for each of m types of moving objects. In block 8 of the calculation of the squares of the deviations in the dimensions of the moving object, the sum of the squares of the deviations of the measured width and length of the detected moving object from the mathematical expectations of the width and length corresponding to each of the m types of the moving object is calculated by the formula:

$${\Delta }_j={\left(D_i^{*}-M\left[D_j\right]\right)}^2+{\left(S_i^{*}-M\left[S_j\right]\right)}^2,(3)$$

where j = [l, m] is the type number of the moving object.

The values of the squares of the deviations of the dimensions of the moving object Δ _j for each of the m types are received in the block 9 for determining the type of the moving object, in which they are compared and the type number of the moving object k is determined, which corresponds to the minimum value of the squares of the deviations:

$$k=\arg \underset{j}{\min }{\Delta }_j(\mathrm{four})$$

The type number of the moving object k is transferred to the register 11, where it is written into it, thereby creating the second part of the record of the reconnaissance catalog, the data from which can later be used, for example, to solve the task of target distribution, moreover, recording possible coordinates of the location of the detected moving object (X _pi , Y _pi ) and its type k into register 11 is made by a clock signal from a clock generator 1.

The number of generating pulses of the clock generator 1 corresponds to the number n cells of the shift register 5, and the number of generating pulses of the clock generator 7 corresponds to the number m cells of the shift register 5. At the end of generation, the required intelligence catalog was formed in register 11.

Thus, thanks to the introduction of new blocks and links, the required technical result is achieved - the expansion of functionality by modeling the intelligence catalog of heterogeneous moving objects.
