基于二次规划的FMCW雷达网络多目标定位算法

FMCW Radar Network Multi-Target Localization Based on Quadratic Programming

针对FMCW雷达网络几何定位方法，在多目标场景下非线性方程求解难度增大和虚假目标急剧增多的问题，提出一种基于二次规划的多目标定位算法，将求解非线性方程转化为通过求解两次寻优问题。仿真实验验证了算法的有效性。本算法可以应用在近程非协作目标定位跟踪算法中目标初始化阶段和新目标生成阶段。

Considering the issue of the adding difficulty in solving nonlinear equations and the increasing ghost target number on multi-target localization rightly in the geometrical locali- zation algorithm of FMCW （frequency modulated continuous wave） radar network,we pro- pose a framework to analyze target localization based on quadratic programming. The nonlinear equations are transformed by solving two-time optimization problems. Then the algo- rithm is simulated and the validity of the algorithm is demonstrated. This algorithm can be applied in various fields of short-range non-cooperative target location, and can also be used in the target initialization stage of tracking algorithm and the new target generation stage in target management.
