The module, together with the software (software) of the product, is a training device that provides the operation of self-propelled anti-aircraft guns (ZSU) in the training training mode (search operator-gunner and range operator) in the primary radar environment simulated by the DAC without turning on the radar transmitter instrument complex (RPK) ZSU. The module is based on a two-layer printed circuit board in the format 160x233 mm and occupies one installation place in the computer system unit.

On the front panel of the module are two connectors of type SNP268 (X3, X4) for connecting signals from a radar station (radar) and a relay command unit (DBK).

The module is connected to the computer bus via two ninety-six-pin connectors type SNP306.

The mass of the module does not exceed 0.3 kg.

The radar simulator of the module according to the data provided by the computer provides the output of pulses to the radar equipment to form on the screen an all-round visibility indicator (PPI) of the passive jamming sector (SPS), local jamming sector (SMP), and the noise interference sector (UWB) and five goal marks (OC).

If the current azimuth of the radar antenna coincides with the azimuth of the OTs or interference sector, the simulator generates the following signals with an amplitude of 2.4 to 3.8 V on the radar with a start frequency:

a) pulses of five target marks with a duration of 0.5 μs with a delay relative to the front of the trigger pulse of the corresponding range to the target, when the elevation sector of the target’s mark falls into the scanning sector of the antenna beam by elevation

b) pulses of the passive jamming sector (SPP) with a duration proportional to the difference between the final and initial ranges [DkSPP - DnSPP], delayed relative to the leading edge of the trigger pulse for a time corresponding to the range Dp SPP, when the passive jamming sector gets into the beam scanning sector by elevation angle;

c) pulses of the local interference sector with a duration proportional to the difference between the final and initial ranges [DkSMP - DnSMP], delayed relative to the leading edge of the trigger pulse for a time corresponding to the range DнСМП. The position of the interference in elevation 1 _k = 0;

d) the signal of the relay command to turn on the noise interference sector.

The formation of the position of the video pulses of the OTs in range is ensured with a resolution of 12.50 m, interference sectors - with a resolution of 100 m.

- multiple mechanical shock with a peak shock acceleration of 15 g and a duration of 5 to 15 ms.

The average MTBF of a module is at least 50,000 hours.

Computer module interaction

The exchange between the computer and the module is initiated by the computer in a double-byte access cycle in the address space area: 100 N.

The module address is set by a programmable constant in a programmable logic integrated circuit (FPGA).

The module contains 19 registers of available computers for writing and reading, except for the register of input commands, available only for reading.

To ensure the operation of the DAC in the training training mode, the central processor of the Baguet computer system sends the following data to the radar simulator of the module:

- the range of five simulated target marks - Dс with a resolution of 3.125 m in the range from zero to 19.2 km;

- the initial range and the final range of the passive sector and the local interference sector (SPP and SMP) - Dn SPN, DK SPN, DN SMP, DK SMP with a resolution of from zero to 19.2 km;

- elevation angles of the start and end sectors of marks and targets NGN - εn, ε with respect _to the upper radar scan antenna sector boundary with steps of 0.059 degrees in a range of zero to 15 degrees;

- labels for the presence of OTs, SPP, NSR and UWB at the current azimuth of the radar antenna.

The values of the ranges and elevations of the targets and interference sectors of the NGN, UWB are issued to the registers of the SAR simulator as these values are updated. The values of the ranges of the NSR are issued as they change at the current azimuth.

Marks for the presence of target marks and interference sectors (NGN, NSR, UWB) are generated and issued if there are target sectors or interference at the current azimuth, and the NSR label is issued only if the elevation axis of the radar antenna axis is less than 7.5 degrees (NSR elevation angle is zero )

Relay commands are issued from the main line of the computer to the register of output relay commands of the simulator.

Relay commands are entered into the computer from the register of input relay commands.

The TNA interface device has current coordinate counters Xt, Yt. Counters X, Y are available for reading by computers and can be used to control the path of exchange of a simulator with a computer.

The module interacts with the radar station using signals:

INC - the momentum of the beginning of the swing,

IR - swing pulse,

KIC - the pulse of the end of the swing,

FROM - start impulse.

Module interaction with the relay command block (DBK)

Data exchange with the block of relay commands (DBK) is performed by signals with TTL - logic levels through connector X3 of a module of type SNP268-37.

The active signal level at the module input is low.
