本文指出了将相控阵技术引入最大信号法测角系统中而出现的某些新问题,分析了由于扫描而产生的波束参数的不稳定性给本测角系统造成的有害影响。着重指出了天线增益的变化有严重危害,因此阵面在扫描过程中良好地匹配,将显得分外重要。分析表明,束宽的变化所带来的有害影响,可借助于某些波控方式,予以克服。但是波办图形的畸变(在扫描过程中必须会产生的)所引起测角精度的下降,则无法避免;文中对此作了粗略的估算。
This paper points out some new problems that arise when phased array technology is introduced into the maximum signal angle measurement system and analyzes the detrimental effects of instability of the beam parameters due to scanning on the system. Emphatically pointed out that the change of the gain of the antenna has a serious harm, so the front surface of the scanning process to match well, will become extremely important. The analysis shows that the deleterious effects of changes in beam width can be overcome by some means of wave control. However, the wave pattern distortion (must be generated during the scanning process) caused by the decline of the accuracy of the survey, it can not be avoided; this article made a rough estimate.
