RADARs with fixed carrier frequency profile are vulnerable to jamming. Changing the carrier frequency of the RADAR by sensing the channel condition dynamically. Frequency agility is one of the best techniques used for anti jamming. Self adaptive frequency agility analyze jamming spectrum real time so that to control the radar transmission frequency. Frequency agility refers to the radar's ability to rapidly change its operating frequency in a pseudo-random fashion to maintain a narrow instantaneous bandwidth over a wide operating bandwidth. The total architecture was implemented on FPGA board with hardware description language and the results are seen in Chip Scope pro analyzer.
