The method of accuracy test for fire-control radar by means of position differential GPS positioning technique is described in this paper. On the basis of test data, the feasibility of positioning data provided by position differential GPS positioning technique as truth was demonstrated. Processed results of the measured data show that the accuracy of data provided by position differential GPS positioning technique is as following: Relative position error is less than 5m(RMS); The azimuth error is less than 0.2 mil (RMS) as the distance is more than 25km; The heading error of the target is less than 3 mil (RMS); The velocity error of the target is less than 0.1m/s(RMS).

It is the first time for TWS(track-while-scan)technology to be applied to the airborne fire control radar in China.The digital tracking filter is one of the most important parts of it.With the limitation of memory size and CPU speed of the airborne radar computer,it is quite needed to choose a real-time track- ing filter with higher accuracy and less computation to enable the radar to track multiple maneuvering tar- gets. This paper deals with three kinds of digital filters which are frequently used in engineering pro- jects.Based on a typical moving track of targets,a series of Monte Carlo simulating test is carried out by com- puter.The simulating data are processed by means of statistics and diagram analysis.The filtering error curves are demonstrated to give an explicit comparison.It comes out that the stage-constant-gain α-β-γ filter (involving a maneuvering detector)has better tracking performance and less running time which is about 15% of Karlman filter.

TWS(边扫描边跟踪)技术在我国机载火控雷达中的应用尚属首次,而数字跟踪滤波器是 TWS 技术中的重要组成部分。在机载雷达计算机容量与速度均受到限制的情况下,为了使雷达具备跟踪机动多目标的能力,选择一个跟踪精度较高且运算量较小的实时跟踪滤波器是完全必要的。本文对工程上常用的三种数字滤波器,以一条典型的目标运动轨迹为例,在计算机上进行了一系列 Monte Carlo 仿真试验,并对仿真结果进行了数理统计,列表分析以及滤波误差曲线直观比较。据此可知,分段常增益α-β-γ滤波器(带机动检测器)对机动目标的跟踪性能较好,且运算量较小,约是卡尔曼滤波的15%左右。
