Target Localization Algorithm Using Guide Source Based on Gabor Filters

Xu Guojun,Da Lianglong,Li Yuyang,Zhang Lin(Department of Navigation and Communication,Navy Submarine Academy,Qingdao,266071,China)  
To achieve the distance location precision by the target localization algorithm using a guide source(GTL algorithm) under the low signal-to-noise(SNR) rations condition,based on the theory of the GTL algorithm and the simulation result characteristic of the GTL algorithm under low signal-to-noise(SNR) condition,a denoise processing method for the GTL algorithm using the Gabor filter method is proposed.Some guide and objective sources with different SNRs are used.The GTL algorithm is simulated.Simulation results before-and-after denoise processing are analyzed.Simulation results show that the distance location efficiency of the GTL algorithm is improved by the denoise processing using the field average method.
