船载单脉冲雷达快速标校系统设计与实现

Design and Implement on Quick-Calibration System of Ship-borne Mono-pulse Radar

摘要:

当前船载单脉冲雷达幅相一致性标定方法受各类条件的限制，不具备快速标校的特性，一旦设备出现故障或系统更换备件时难以满足系统标校的需求。针对此问题在介绍船载单脉冲雷达幅相一致性标定原理的基础上对传统标校方法进行了分析。基于多模自跟踪体制，建立了天线偏离角与角误差信号关系的数学模型，通过获取目标相对天线角度变化值以及角误差电压变化值，提出了一种幅相一致性快速标定的新方法，并研制了快速标校软件，对设备进行多次标定试验，结果表明标校过程快速简便，满足精度指标，对提高幅相标定效率、克服标定环境局限性等具有重要的现实意义。

Abstract:

In this paper, the theory and design of mono-pulse radar amplitude-phase calibration are introduced and the traditional methods of amplitude-phase calibration are analyzed. Based on the system of multi-mode tracking, the mathematical model of the relation between deviation angle and error voltage is built. Through obtaining the variation value of deviation angle and error voltage, a new method is determined, which is used to calibrate the amplitude and phase consistency. It has important practical significance for improving the efficiency of amplitude-phase calibration, as well as overcoming the limitation of the calibrating environment.
