Target probing based on wideband pulse radar is a challenging task for radio frequency simulation (RFS) in anechoic chamber. Due to the long time duration of pulse radar signal and the limited space of anechoic chamber, the reflected signal returns before the pulse radar signal is fully transmitted, which makes it difficult for the signal reception. As a consequence, the target high-resolution ran...Show More
