| 脱靶量测量系统在考核导弹末段效能时有着十分重要的作用，广泛应用于各型武器系统的定型试验和部队演习打靶计分。设计了一种基于线性调频连续波（LFMCW）雷达体制的标量脱靶量测量系统，利用回波信号与本振信号之间的频差对目标进行测距，然后通过最小二乘算法求解目标与雷达之间的最小距离，即脱靶量。具有成本低、体积小、重量轻、峰值功率小和测量精度高等特点，可适用于无人机、靶弹、靶船等多种靶标平台。该系统装于靶船上，对某型反舰导弹的脱靶量进行实弹检验，检验结果表明，该系统方案切实可行，且脱靶量测量精度优于1m，可有效应用于导弹标量脱靶量测量。 |

| Abstract: |
| Miss distance measuring system is very important in the assessment of missile terminal performance and has been widely used in the equipment approval tests of various types of weapon systems and the targeting score for military exercises. A scalar miss distance measuring system based on LFMCW radar is proposed in this paper. The target’s distance is measured by using the frequency difference between the echo signal and the local oscillator signal, and the minimum distance of target, namely the miss distance is solved through the least square fitting. The proposed system has the advantages of low cost, small volume, light weight, low peak power, and high measurement precision, and can be loaded on a variety of drone platforms. The system was loaded on a target ship for measuring miss distance of a type of anti-ship missile. The measurement result shows its feasibility and high measurement precision. It can be effectively used in scalar miss distance measuring of missile. |
