Spatial Spectrum Estimation, Frequency and DOA Cascade

Abstract- 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
