多宽带雷达协同目标微动周期估计方法
Collaborative estimation method of target micro-motion period via multiple wideband radars
摘要
Abstract
Micro-motion period is a significant feature to distinguish warheads from shape-decoys.At pres-ent,the main estimation methods of radar target micro-motion period have some shortcomings,such as large con-sumption of time resources,high requirement of single radar measurement accuracy and demand of multi-radar synchronous observation.In order to address the above problems,this paper proposes a collaborative estimation method of target micro-motion period via multiple wideband radar sets.First,the least mean square(LMS)algo-rithm is applied to estimate the actual size of the target,and then a mutative scale frequency mixing algorithm is employed to extract the target micro-motion period from the size sequence.Finally,the effectiveness of the pro-posed method is verified by simulation,and the application boundary conditions are also explored.This method does not require multiple radar sets to observe simultaneously,but can accurately estimate the target micro-motion period under the conditions of conventional dimension measurement accuracy and time resource consumption of single radar.关键词
