摘　　要：单脉冲自动测角包括确定角误差的大小及角误差的符号,通过一种改进方法,不需要解算和信号与差信号的相角就能确定角误差符号,根据角误差大小及符号采用S曲线查表法,可以实现对角度的精确测量,从而在保证高精度情况下,节约了TS201的处理时间和存储空间。文中采用一片TS201实现某机载雷达所需要的测角系统,该设计满足实时性要求,具有精度高、自动测角、实现简单、稳健性好等优点。The automatic Angle Measurement of Monopulse includes confirming the value and sign of the angle error.By an improved method,the sign of the angle error can be fixed out without solving the phase of the sum signal and differential signal.According to the value and sign of the angle error,the exact measure of an angle can be realized by finding the S curve table.Therefore,the processing time and storage space of TS201 would be saved greatly with high accuracy.In this paper,a TS201 is used to meet the requirement of an angle measurement system for airborne radar.The design has the advantages of good real-timeness,high accuracy,automatic measurement of the angle,easy realization and good stability.
