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.
