Abstract: The current work is aimed to fabricate a pulse generator to meet the requirements of control and process signals to be applied on to several basic constituting functional units of a radar system. The functional units of Radar system includes Exciter, Receiver, Radar Controller, TCSG and Duplexer Antenna.The synchronized pulses generated are operate on functional units is accomplished by generating a reference pulse known as “Inter pulse period”. The controlled pulses in the radar systems are categories as Exciter pulse, Transmit pulse, Gating pulse, Blanking pulse and are generated with respect to “Inter pulse period”. All these functions of the different control signals generated for the functioning of radar is conveniently done by FPGA system using Spartan 6.Pulsed radar transmits high power, high-frequency pulses toward the target. Then it waits for the echo of the transmitted signal for some time before it transmits a new pulse and it can be used to measure target velocities. Target Range and bearings can be determined from the measured antenna position and time-of-arrival of the reflected signal.Pulse generator is the equipment that are used to generate pulses - normally rectangular pulses, these pulses can be used to generate pulses that can stimulate logic circuit.These different pulses can be generated by using FPGA, it can be programmed to the desired application or functionality requirements.
