Abstract: Jamming is one of the main problems for the functioning of the radar. Surveillance radar or searching radar has to overcome the jamming environment during the operation of the work. Jamming is of Diversified which includes narrow band, wide band jamming or its combination. Hence the solution for the Diversified jamming is obtained by using fast self switching frequency agility technique and its function is very effective. The detailed steps to achieve this function are described and the function is realized with FPGA using Hardware Description Language.The practical application on a surveillance radar shows that the module has good real time and anti jamming capacity. Modelsim will be used for functional simulation and results verification. Xilinx ISE will be used for synthesis; place & route and bit file generation. Xilinx FPGA board will be used for results verification.
