The DF/LPI-DF Processor is specifically designed to process videos generated by weak RF signals (either CW or large pulse) which are radiated by different types of Radars including LPI RADARS. This board has the capability to extract signals in the presence of large amount of noise. It contains 8 ADCs followed by XILINX VIRTEX -5 Series FPGA. The processor board can process upto 8 Video inputs for amplitude based DF systems or 4 pairs of Video inputs for phase based DF systems. The processor board has the capability to process pulse width down to 50ns.
