In order to synthesize a desired spatial beampattern, which is mapped into a waveform correlation matrix, a computationally attractive method is proposed in this paper. This method decomposes the correlation matrix into a spatial direction matrix (SDM) and a temporal division matrix (TDM). Then the SDM is formed by using a set of transmit steering vectors, whose angles can be estimated by MUSIC, and...
In an electronic detecting system, how to capture non-cooperative signal at low SNR is always a challenging work. This paper puts forward a real-time algorithm named Shifted-N points-Correlation Algorithm for detecting LFM (Linear Frequency Modulation) pulse signal based on digital autocorrelation. Applying a gliding window of proper length to truncate infinite signal into finite length, then calculating...
