雷达最大探测距离现场在位测试方法探讨

Discussion on on-site in-situ Testing Method for Radar Maximum Detection Distance

探测距离是雷达的关键参数。由于雷达安装完成后,对发射天线和接收天线的增益很难进行定期测试,因此目前雷达探测距离的定期评价少有实行。提出了一种简单易行的现场在位测试方法以解决这类问题,即通过测量发射功率积和接收功率商来评价探测距离,对于雷达最大探测距离的定期测试具有一定的参考意义。

Detection distance is the key parameter of radar.After the installation of radar,the gain of transmitting antenna and receiving antenna is difficult to be measured regularly,so the periodic evaluation of radar detection distance is seldom carried out at present.Therefore,a simple on-site in-situ method is proposed to solve such problems,that is,the detection distance is evaluated by measuring the transmitting power product and the receiving power quotient,which is of certain reference significance for the periodic measurement of maximum detection distance of radar.
