ADAPTIVE DIGITAL BEAMFORMING RADAR TECHNIQUE FOR CREATING HIGH RESOLUTION RANGE PROFILE FOR TARGET IN MOTION IN THE PRESENCE OF JAMMING

摘要

The transmitter (14) receives a modulated center frequency from the waveform generator/oscialltor (20), which is frequency agile. The antenna (12) transmits radar signals (13) and receives reflected radar signals (15), and then sends received signals (17) to the dechirper (16) and thereafter to the adaptive digital beamformer (18). Beamformed signal (19) are provided to the range bin selector (22). The resultatn signal (23) is fed to the pulse compressor (24). Then the pulse compressed signal (31) is fed to the inverse FFT processor (32) to create an HRR profile.
