摘要

雷达检测性能是雷达最基本、最重要的性能,雷达检测性能试验是雷达试验的重要内容。由于各种原因,针对雷达的系统级原型试验常常难以开展或者只能极少量地开展,通常只能通过进行大量等效试验来辅助雷达性能的鉴定评估工作。本文针对缺乏原型试验条件下的雷达检测性能评估问题,提出了一种基于试验数据分析的雷达检测性能等效推算方法。首先给出了等效试验与原型试验之间的差异性度量方法,它是等效推算和性能评估的基础;接着对存在原型试验条件下的等效推算方法进行了研究;而后针对通常无法进行原型试验的实际情况,提出了一种基于预测模型和仿真试验相结合的零子样原型试验条件下的等效推算方法;最后通过仿真实例验证了本文方法的合理性和可行性。

Abstract

Radar detection performance is the most fundamental and most important performance of the radar, and radar detection performance test is an important part of the radar test. For various reasons, the prototype test of a radar system is difficult to carry out or it can be carried out only on a small scale. A large number of equivalent tests are required to assist the test/identification/evaluation of radar performance. In view of the radar performance evaluation under little or no radar prototype test data, this paper proposes an equivalent calculation method of radar detection performance which is based on test data analysis. Firstly, it studies the measurements of the differences between an equivalent test and a prototype test, which is the basis of equivalent calculation and performance evaluation. Secondly, equivalent calculation methods are stu-died for which a prototype test is carried out. Finally for the actual situation where a prototype test is not carried out, it proposes an equivalent calculation method without prototype test based on fusion of a predictive model and simulation tests. Simulation examples verify the rationality and feasibility of the present method.

Key words： radar; detection performance; equivalent calculation; prototype test; equivalent test; difference
