毫米波合成孔径辐射计末制导技术研究

针对弹上空间小且毫米波器件成本高，提出了把近程毫米波合成孔径辐射计被动成像技术应用于寻的末制导，并给出一种高性能制导系统。该系统采用二维最小冗余线性阵列天线，由7个接收阵元组成，可获得分辨率为6×6的像，大大节约了弹上资源和成本。同时引入了四阶累积量成像算法，不仅可以扩展孔径，而且使系统具有良好的抗噪能力。合成孔径辐射计可以即时成像，不需要扫描，满足制导的实时性要求。通过仿真表明，该系统在近距离时具有良好的探测性能。

Millimetre wave synthetic aperture radiometer terminal guidance technology

As the small space in the shell and the high cost of millimetre wave devices, the near range milli-metre wave synthetic aperture radiometer (MMW-SAR) passive imaging technology is introduced into homing terminal guidance, and then a high performance guidance system is proposed. This system uses 2D minimum redundancy linear array antenna, is composed of seven receiving elements and can give 6×6 pixels image with the resource and cost greatly saved. Meanwhile fourth order cumulant is used, not only extends synthetic aper-ture, but also improves the anti-noise ability. MMW-SAR can immediately give images without scanning, and meets the real-time requirements of guidance. The simulation result shows that this system has a good detection performance under near range conditions.
