Block diagram of the complex
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.
- 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/
- duration of the compressed pulse 1 - 1,2mc.sec.
- level of the maximum sidelobe of the compressed pulse (50–55) dB
- adaptive rejection of clutter with the coefficient of subclutter
visibility:
- 60 dB – on motionless
sources
- 45 dB – on fluctuating sources
- stabilization of the false alarm levels with the automatic control of the
detection threshold
- there is provided a possibility to process information of the weather
channel and the speed selection of the target (on the basis of spectral analyses).
- forming, smoothing, long-term storage of the chart of interferences;
- forming codes of control with sensitivity time control (STC);
- selection of false marks on the combination of indications with the
probability 0,8 – 0,9
- Without processing
- After the system of the detection of moving targets
- After the system of scan-to-scan processing of signals
- 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 3–5 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.
Modern digital element basis, including:
Signal ADSP (Analog Device Signal Processor);
Programmable logical integral schemes of the firm «XILINX»;
ADC board
Processor 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.
