一种针对机动目标的解速度模糊新算法

A New Velocity Ambiguity Resolution Algorithm for Maneuvering Targets

解速度模糊是脉冲多普勒雷达中需要解决的重要问题,通常的解速度模糊算法皆未考虑加速度信息,当雷达跟踪火箭弹等长助推段目标时存在速度解算误差大或无法解算、不能有效预测目标速度信息等问题。针对上述情况,提出一种面向加速度目标的解速度模糊算法。计算机仿真及雷达模拟数据表明,该方法对长助推段目标速度、加速度解算准确度高,对传统目标兼容性良好。该文还给出了新算法的工程实现方法。

Velocity ambiguity resolution is an important problem need to be resolved in pulse doppler radar.The usual velocity ambiguity resolution algorithms all do not consider acceleration information,and there are problems such as large velocity calculation errors or inability to solve,and inability to effectively predict target velocity information when radar tracks rocket shell and other long boost target.Aiming at the above situation,a velocity ambiguity resolution algorithm for acceleration targets is proposed.Computer simulation and radar simulation data show that this method has high accuracy in long boost target velocity,acceleration calculation,and good compatibility with traditional targets.The paper also provides an engineering implementation method for the new algorithm.
