摘要
游标测距技术是一种新颖的相位测距技术,可以提供精密的径向距离测量值,其随机误差小于1/4波长。文中首先讨论了游标测距在线性调频全相参脉冲雷达中应用的可行性问题,然后利用计算机仿真进行了误差分析,最后得出游标测距在线性调频全相参脉冲雷达中应用时所需的测量数据和对该测量数据的要求。
Range Vernier technique is a new phase ranging technique, which can provide radial measurement with rodom error less than one fourth of wavelength. Firstly we discuss the feasibility of applying Range Vernier to linear frequency modulation coherent pulse radar. Then we analyze the error of Range Vernier by computer simulation. At last we findthe needed data and the requirement to the data in applying Range Vernier to linear frequency modulation coherent pulse radar.
