Design and Development of a Low Cost Chirp Generator for Airborne Synthetic Aperture Radar
An airborne C-band Synthetic Aperture Radar (SAR) has been designed and developed over the past few years as a key geometric data source for environmental monitoring by the Centre for Applied Electromagnetic of Multimedia University (MMU), Malaysia. Several modifications and enhancement are underway on top of the successful construction of the current SAR prototype. The highlight of this continuation work is the hardware implementation of the airborne SAR, specifically on the modifications of the existing SAR sensor microwave transceiver, such as the design and development of one high-speed dual-channel chirp generator using a digital approach. The digital approach is selected over an equivalent analogue solution for its stability, repeatability and flexibility following breakthrough and advancement in the world of digital electronics. This paper focuses on the design and development issues concerning the chirp generator.
