Design and implementation of a highly configurable low power robust signal processor for portable ground based “multiple scan rate” surveillance radar

FPGA based realization of a highly configurable low-power robust signal processor for a portable ground-based multiple scan ratesurveillance radar is presented. Portability feature of the radar demands a compact radar system which should be able to detect low flying aerial targets against clutter/interference background. All requirements could be met in a FPGA-based design of a multi-channel signal processor to cater for low peak power large bandwidth waveforms, separate processing for special targets and an embedded softcore processor. Reliable self-test mechanisms – external as well as internal have been built into the signal processor for functional verification of entire radar system.
