진폭비교 이중합차 모노펄스 레이다 시스템의 해석 = An Analysis of Amplitude-Comparison Double Sum-and-Difference Monopulse Radar System

다국어 초록 (Multilingual Abstract)

An analysis of amplitude-comparison lane multiplexing double sum-and-difference system using single channel IF amplifier is made in an attempt to specify the effects certain parameters have on system performance. The pattern of an antenna was discribed by a sinusoidal function for the convenience of analysis. The angle error detection curve has a tangential characteristic from the effect of automatic gain control system in the non-saturated region of the IF amplifier. Post-comparator phase shifts and voltage unbalance have an effect on the slope of the angle error detection curve. The effects of pre-comparator phase shifts are cancelled out in double sum-and-difference system. Only pre-comparator voltage unbalance results in a change of boresight indication. To complete the evaluation, the parameters which affect the receiving equipment performance have also been developed. Equations describing the performance of the system have been derived and system evaluation curves have been plotted using these equations.
