摘要

It is essential and desirable to get a high resolution echo in a radar image without using a large antenna. On scanning a radar antenna, the target's distribution is smoothed by the antenna beam and a smeared echo appears on the radar display. This paper describes three different types of beam compression radars: subsurface SAR; correlation array radar; and inversion processed radar. The experimental results show that the beamwidth on display was effectively compressed by the signal processing
