New programmable digital complex of the equipment for forming and unit-pulse, scan-to-scan, cycle-to-cycle and secondary processing of signals for AORL MTA-85 includes the following systems.

System of forming of the ranging signals (SFRS) provides for:

  • digital precision forming of simple and simple ranging signals (RS) (including those with linear and non-linear FM). Base of complex signals from 30 to 300
  • forming of the variable pulse repetition bursts of the ranging signals in order to burst of the ranging signals in order to achieve uniformity of the speed characteristics within the range between 40 km/hour and 2000 km/hour/

Compression system of the ranging signals (CSS) provides for:

  • duration of the compressed pulse 1 - 1,2mc.sec.
  • level of the maximum sidelobe of the compressed pulse (5055) dB

System of the detection of the moving targets (MTDS) provides for:

  • adaptive rejection of clutter with the coefficient of subclutter visibility:
  • 60 dB on motionless sources
  • 45 dB on fluctuating sources

    • Without processing
    • After the system of the detection of moving targets
    • After the system of scan-to-scan processing of signals

    The system of the informations secondary processing (ISPS) provides for:

    • the total number of the tracked targets not less than 250 (with 10 targets within the beam)
    • total number of the processed marks during a survey 1000.
    • probability of the path connection at the range 0,7 0,8 from the detection range not less than 0,8 0,9;
    • time of the false paths existence not more than 35 surveys;
    • probability of the selection of signals from low-speed target, which came to the exit of the selection of moving targets systems not less than 0,8.

    There are used in the development:

    Modern digital element basis, including:

    Signal ADSP (Analog Device Signal Processor);

    Programmable logical integral schemes of the firm XILINX;

     

    ADC board

    • The whole equipment is mounted in the industrial chassis of the PC-610;
    • Reliability of the complex not less than 40000 hours
    • There is available a built in system of testing and control
    • There are wide upgrading possibilities within the complex; reloading of algorithms and programs is allowed
    • Adaptive functional algorithms supercede foreign analogs.
