Data acquisition and processing system for searching and tracking radars
The system is based on a DSP developer kit produced by SET Ltd company, which contains Xylinx's FPGA of Virtex1000E type, DSP TI320C6202, PCI interface, and a triple-channel analog-to-digital converter. The system performs the following functions:
- Clock transmitter and receiver units,
- Analog-to-digital conversion of received signals,
- Digital quadrature demodulation of received signals,
- Automatic gain control and equalization of the amplitude and phase characteristics of the receiver channels,
- Coherent averaging of received signals based on FFT with the length of 16, 32, 64 points,
- Clutter suppression by using IIR filter of a six order in each gate,
- Production of control signals for handling antenna steering mechanism to provide scanning, target detection, and target tracking modes,
- Production of data for radar image displaying, including mapping.
The system provides executing of these functions in real time with the following parameters:
| Pulse repetition frequency | 1...10 kHz |
| Number of gates | 5000 |
| Pulse duration | 0.3...1 msec |
| ADC Resolution | 12 bits |
| Sampling rate | up to 70 MHz |
| Number of digital receiver channels | 3 |
