北航飞行控制系统第一次大作业，包括源代码和作业报告，都是经过调试，可以运行的，作业报告是按要求写的。(The First assignment of Flight Control System in Beihang University)

介绍无源定位的方法，对于无源定位和误差分析极有帮助。(Introduced the method of passive location, location and error analysis for the passive extremely helpful.)

从雷达目标接收的信号通常埋在 热噪声和杂波。正如杂波加噪声电源 不知道先验，固定的阈值检测方案不能 假警报才会应用于雷达回报 控制。(The signal received from a radar target is usually buried in thermal noise and clutter. As the clutter-plus-noise power is not known a priori, a fixed threshold detection scheme cannot be applied to the radar return if the false alarm is to be controlled.)

Example of a two-dimensional Gabor filterIn image processing, a Gabor filter, named after Dennis Gabor, is a linear filter used for edge detection. Frequency and orientation representations of Gabor filter are similar to those of human visual system, and it has been found to be particularly appropriate for texture representation and discrimination. In the spatial domain, a 2D Gabor filter is a Gaussian kernel function modulated by a sinusoidal plane wave. The Gabor filters are self-similar – all filters can be generated from one mother wavelet by dilation and rotation
