An approach to sample broadband radar signal with low-rate ADC using adaptive beamforming technique

To directly sample broadband radar signal with high-rate analog-to-digital converter (ADC) suffers from high cost and low sampling precision. In this paper a novel method is presented to sample a wide-band signal with multiple low-rate ADC channels by using adaptive beamforming technique. This method has the advantages of low cost, low sampling; rate, high precision, easy implementation, and it is robust to channel errors. The effectiveness of the proposed approach is verified by simulated data
