测控雷达布站与雷达精度试验航路设计研究

Research on Measurement Radar Distribution and Radar Accuracy Test Route Design

雷达测量是靶场测控的重要手段之一,在进行雷达精度试验时,由于测控雷达布站位置与所需鉴定雷达不同,需将测控雷达坐标系下的数据转换到被鉴定雷达坐标系下,而由于坐标的转换,目标位置误差被放大,因此必须对转换后测控雷达的精度进行误差分析,以确保其测量精度满足试验数据处理要求精度。建立了目标位置、靶场测控雷达和被鉴定雷达位置分布与测量精度误差关系的数学模型,并仿真分析了测控雷达的分布和目标航路的设计对测量精度误差的影响。

Radar measurement is an important measure for the range measurement. In the radar accuracy test, due to the different locations between the measurement radar and the radar to be certificated, the data of the measurement radar needs to be transformed to the coordinate system of the radar to be certificated. The transformation amplifies the error of target location. To ensure the accuracy requirement of the data processing, accuracy error analysis is necessary. The mathematical model is established on the relation among the target location, the measurement radar and the location and accuracy error of the radar to be certificated. The effects of the measurement radar location and the target air-route design on the accuracy error are analyzed by simulation.
