The Digital Instantaneous Frequency Measurement (DIFM) receiver is capable of
measuring the frequency of input RF signal almost instantaneously using Single FPGA and High Speed ADCs (The only delay is a latency of 4 clock cycles of 40MHz). The input frequency range can be from 500MHz to 2500MHz, the sensitivity of the DIFM receiver is better than -70dBm down pulse widths of 50ns.
It has a built in high sensitivity CW circuit. Feature like detection of Pulse on pulse (POP), Pulse on CW, Phase coded signals, and FMCW can be incorporated depending on customer requirement. It is also possible to provide 6 to 10 dB higher sensitivity for large pulse widths and CW signals based on customer requirement. The processor board can also be used for other frequency bands up to 18GHz and beyond.
Other Specifications can also be achieved depending on Customer Requirements.
The DF/LPI-DF Processor is specifically designed to process videos generated by week RF signals (either CW or large pulse widths) which are radiated by different types Radars including LPI RADARS. This board has the capability to extract signals in the presence of large amount of noise. It contains 16 ADCs followed by XILINX VIRTEX Series FPGA. The processor board can process upto 16 Video inputs for amplitude based DF systems or 8 pairs of Video inputs for phase based DF systems. The processor board has the capability to process pulse width down to 50ns.
Other Specifications can also be achieved depending on Customer Requirements.
