多跳频脉冲的高效测向算法
An effective direction finding method for multi-frequency hopping pulses
摘要
Abstract
Based on time-frequency matrix decomposition, an effective direction finding method was proposed for multi-frequency hopping pulses. A time-frequency array model was constructed by effective cross-SPW Distribution of the reference and other sensors＇ output. Accordingly, the spatial time-frequency distribution (STFD) matrixes are formed by time-frequency points residing on their own power concentration regions of the frequency-hopping pulses. The directions were estimated by ESPRIT after singular value decomposition of the STFD matrix. The proposed method can deal with coherent signals and has low complexity in both matrix construction and time-frequency distribution computation. The simulation results show the efficiency of the method.关键词
