The concept of pulsed RADARs is associated with Chirp Signal Transmission. Chirp signal provides high precision in target resolvability with the flexibility of lower average power. The transmitted Chirp Signal defines the resultant image resolution, which varies from mission to mission. The objective of this paper is to discuss the implementation of a FPGA based runtime user configurable Chirp Signal Generator using the Xilinx System Generator. The designed system is capable of transmitting three different types of Chirp Signal; i.e. Unidirectional Up-Chirp, Unidirectional Down-Chirp and Bidirectional Chirp. The system can generate an output Chirp of Bandwidth between 10 to 100MHz with a transmitted pulse duration of between 1 to 10 Micro Seconds and a Pulse Repetition Frequency of between 100 to 10000Hz. The sampling frequency of the system is kept constant at 150MHz.
