干涉仪测向原理及影响试验要素研究

摘要

在装备试验鉴定中测向精度是雷达侦察装备的重要考核指标,论文介绍干涉仪测向技术原理,针对一维干涉仪对高仰角目标的误差主要来源进行分析与计算.为考查误差因素对靶场试验的影响,设计一维干涉仪装备对高空机载雷达目标测向试验典型态势,分析不同距离和仰角条件下的测向误差数据,并提出试验和装备使用建议.%The accuracy of direction finding was an important test index of the radar reconnaissance equipment in the range test. The principle of interferometer direction finding was analyzed and the main error source for the high elevation angle target in the one-dimensional interferometer equipment was analyzed and calculated. The typical test situation in which the high altitude airborne radar was used for testing the one-dimensional interferometer equipment was designed for investigating the influence of the error fac?tors in the range test. The error data in the different distance and elevation angle was analyzed and at last the experiments for test and forthputting were put forward.
