介绍了一种单脉冲跟踪新方法。该方法利用正弦空间变换,将单脉冲角敏函数在天线阵面坐标系中随扫描角的非线性变化特征转变为正弦空间中简单平移的线性变化特征,使得二维相扫测角系统在装订角敏函数时,方位和仰角仅需各装订一条曲线,不仅节约了大量存储空间,而且消除了分区装订和波控机量化引入的误差,极大地提高了雷达跟踪精度。

[Abstract]
A new method for the monopulse track is introduced. By use of the sinusoidal spatial transform, the method transfers the nonlinearly variational characteristics on monopulse angle sensitive function versus scan angle in antenna array coordinate to a simple linearly shift one in sinusoidal space. While binding angle sensitive for 2 D phased array, it need binding only a curve in azimuth and elevation plane. Not only the access and storage spaces are reduced, but the quantization errors due to partition and beam controller are illuminated. The radar track precision is improved obviously.
