Design of X-Band FMCW Radar Using Digital Doppler Processor

RADAR is an electromagnetic sensor used to detect and locate the target. An FPGA based X-band FMCW radar system will be built with digital Doppler processor and used for detection of target, localization, Doppler processing, velocity calculation and Synthetic Aperture Radar (SAR)/Inverse SAR (ISAR) imaging etc. This radar is a ground based stationary ballistic radar, which transmits a sweep of frequency with a variable Pulse Repetition Frequency (PRF). Return signals called as echo from the target is processed to find the information about their location and velocity. Discrete RF components will be used in the transmitter and receiver chains. The hardware solution is based on Xilinx FPGA board which is responsible for the control of radar system and the digital signal processing of the received signal that involves a Constant False Alarm Rate (CFAR).
