Abstract
The article describes technical realization of compact UAV based X/L-band SAR. It presents a block diagram of the developed radar prototype and describes the structural diagrams of the main functional blocks: the signal generation and processing unit, the coordinate processing unit, the radar image generation unit. The estimation of the resources required for the implementation of signal processing of a programmable logic integrated circuit (FPGA) is given. Examples of radar images obtained during full-scale tests of the radar prototype are given at the end of the article. Novelty of design based on two main factors: broadband quasi-continuous signals (QCS) and the real-time land surface imaging. The usage of QCS leads to the higher stealthiness and noise-immunity. The peak power of transmitter is decreased also. This features are highly demanded while designing RSA systems that can be used on compact UAV.
