摘要/Abstract

摘要：

雷达检测性能与目标回波特性相关, 设计与目标角域起伏特性相匹配的波形频率可以提升目标的检测概率。对此, 提出一种基于启发式频率规划的多雷达波形设计算法。在离线状态下, 通过起伏因子约束下角域划分、起伏因子最大化角域关联和异常角域决策三步设计匹配机动目标特性的角度频率匹配集。在目标跟踪阶段, 通过多站雷达扩展探测频率以优化角域, 并根据机动目标在状态转移区域内的滤波预测状态值完成目标回波不确定条件下的雷达节点和辐射频率参数规划。仿真结果表明, 所提算法在飞机进行匀速直线与协同拐弯交替运动的跟踪场景中检测性能显著提升。

Abstract:

Radar detection performance is related to target echo characteristics, and the detection probability of target can be improved by designing waveform frequency matching with the angular domain fluctuation characteristics of target. In this regard, a multi-radar waveform design algorithm based on heuristic frequency domain programming is proposed. In offline state, the angle frequency matching set for matching the characteristics of maneuvering targets is designed in three steps: angle domain division under fluctuation factor constraints, maximizing angle domain association with fluctuation factors, and abnormal angle domain decision-making. In the target tracking stage, the multi-station radar extends the detection frequency to optimize the angular domain. According to the filter predicted state value of maneuvering targets in the state transition region, the radar node and radiation frequency parameter programming under the condition of uncertain target echo is completed. Simulation results show that the detection performance of the proposed algorithm is significantly improved in the tracking scenario of alternating motion of uniform straight line and cooperative turning.

Key words: maneuvering target, target characteristic, heuristic method, frequency programming, multi-station radar
