毫米波测速雷达的测速原理

介绍了一种毫米波测速雷达系统的工作原理，该系统采用高精度谱分析法测量外弹道弹丸速度曲线，并利用最小二乘法拟合方法推出弹丸的初速．分析了测速误差、精度与测点数、外推步长的关系．该系统将毫米波技术成功应用于火炮或枪支的内、外弹道参数的测试．通过与国外同类产品测试比对，证明该系统具有较高的测试精度。

THE PRINCIPLE OF MICROWAVE VELOCITY RADAR

The principle of a kind of microwave velocity radar system with high accuracy spectrum analysis method to measure external trajectory curve was introduced. The initial velocity was calculated by minimum two multiplications method. The relation between the test accuracy with the number of measure spots and calculation step length was analyzed. The microwave technique was applied successfully in the internal or external ballistic parameter tests of artillery or guns with this system. Compared with the same kind products abroad, it was proved that the system has the high precision.
