Broadband Radar Signal Multi-channel Sampling Based on Adaptive Beamforming Technique and Performance Evaluation

摘要

To directly sample broadband radar signal with high-rate Analog-to-digital Converter (ADC) suffers from high cost and low sampling precision. A novel method is presented to sample a wide-band signal with multiple low-rate ADC channels by using adaptive beamforming technique in this paper. 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.
