| 摘 要： | 从理论上分析了单脉冲雷达测角回路在开环时 ,角误差出现鼓包的机理 ,并指出这是一种不可避免的现象 ,只有减少零值偏移 ,才能使鼓包的幅度下降 ,如果零值偏移减少到热噪声电平之下 ,则可以不考虑其对雷达性能的影响。

| Abstract: | In this paper, great envelop angle error is analyzed theoretically in monopulse radar in its angle open loop state. Study shows this phenomenon is inevitable. Only decreasing the false zero can the amplitude of envelop be decreased. After the false zero being decreased beneath the noise, its effect on radar can be concealed. |
