Digital on-line compensation of errors induced by linear distortion in broadband LFM radars

摘要

The problem of group delay distortion in last generation LFM (linear frequency modulation) radars has been identified as an important handicap for the development of high performance broadband systems. A simple digital calibration technique is now proposed to overcome this problem. Although it has been developed for pulsed synthetic aperture radars it can be easily applied to other LFM systems.
