| Abstract: | This paper presents the scheme,function and technical specifications of170-325GHz waveband radar cross sec-tion(RCS) measurement system.Some steps are taken to improve the performance of the system,including multilevel ampl-i fication and frequency multiplication,low-order harmonic mixing,using external signal generators and intermediary fre-quency(IF) receiver.Considerable dynamic range and other characteristics are obtained with these approaches.Finally,the concrete implementation and experiment of1mm RCS measurement system are described,and feasibility of the system stud-ied in this paper is verified. |
