基于重采样的水下小目标多基地量测融合
Multistatic measurement fusion for underwater small targets based on resample
摘要
Abstract
Aiming at the influence of the interference measurement to multistatic measurement fusion for underwater small targets, the multistatic measurement fusion algorithm based on resample is proposed. The random samples which are obtained by resample approximate probability density distribution. Finally, the equivalent measurement in multistatic system is obtained following fusion process of the random samples. The simulation test and performance analysis are con-ducted. The increase of interference measurement density leads the reduction of the fusion accuracy and the increase of the operating time, while the increase of grid number improves fusion accuracy and increases operating time. Then the algo-rithm is utilized for the data processing of realistic experiment. The results show that the multistatic measurement fusion algorithm based resample process yields more precision equivalent measurement of the least root mean square error in sta-tistical sense comparing with the fused measurement of monostatic sonar. The algorithm provides more reliable data for the centralized fusion tracking of underwater small targets.关键词
