Investigation on Space-Time Signal Processing Technology Based on Data Channelization

摘要

High accuracy of parameter estimation and real-time processing is difficult in electronic support management signal processing with low SNR(Signal-Noise-Ratio). Traditional algorithms can be only effective for high SNR. In this work, classical spatial spectrum estimation is integrated with data channelization and a frequency and DOA (Direction-of-arrival) cascade estimation method based on data channelization is proposed. The simulations show that the algorithm is effective for SNR of -10 dB and the computing speed is improved.
