Description: A filter bank structure that can deal effectively with piecewise smooth images with smooth contours, was proposed by Minh N Do and Martin Vetterli. The resulting image expansion is a directional multiresolution analysis framework composed of contour segments, and thus is named contourlet. This will overcome the challenges of wavelet and curvelet transform. Contourlet transform is a double filter bank structure. It is implemented by the pyramidal directional filter bank (PDFB) which decomposes images into directional subbands at multiple scales. In terms of structure the contourlet transform is a cascade of a Laplacian Pyramid and a directional filter bank. In essence, it first use a wavelet-like transform for edge detection, and then a local directional transform for contour segment detection. The contourlet transform provides a sparse representation for two-dimensional piecewise smooth signals that resemble images. Platform: |

Description: 车辆监测用测速雷达是依据多普勒效应原理实现的。由雷达发出一束微波，遇被测目标（车辆）时微波被反射回来，再由雷达接收反射波。如果目标相对于雷达有距离上的运动，反射波的频率将与发射频率发生差异，而这种差异的大小正比于目标与雷达的相对运动速度。于是，雷达通过检测反射波频率和发射波频率的差，就可以计算出被测车辆的移动速度。本次课程设计是利用离散付里叶变换进行频谱分析，设计数字滤波器组，并对滤波器组加窗降低副瓣，通过频域方法测量速度。-Vehicle monitoring using radar gun is based on the realization of the principle of the Doppler effect. By the radar emits a microwave, in case the measured target (vehicle) when the microwave is reflected back, and then by receiving the reflected radar waves. If the target relative to the radar on a distance of motion, the frequency of the reflected wave and the emission frequency of the difference, and this difference is proportional to the relative target and radar velocity. Thus, by detecting the reflected radar wave frequency and the frequency difference between the transmitted wave, we can calculate the movement speed of the vehicle under test. This course is designed to take advantage of the discrete Fourier transform spectral analysis, digital filter design group, and filter bank windowed lower sidelobes by frequency domain methods to measure speed.

Description: 很好的GPS/INS超紧组合导航的文章，关键词：GPS,INS，超紧组合导航，抗干扰-The performance of an Ultra-Tightly Coupled
(UTC) Global Positioning System/Inertial Navigation System
(GPS/INS) is evaluated using a system simulation of the GPS
receiver and navigation processing. The UTC system being
analyzed uses a bank of pre-filters to estimate code delay error
and Doppler frequency error for each satellite. These outputs are
sent to a central Kalman navigation filter. This central processor
generates estimates of inertial navigation position, velocity, and
attitude errors IMU biases and user clock errors, which are
used to correct the navigation solution. In the UTC approach,
outputs from the central navigation processor, after projection
into satellite line-of-sight coordinates, are used to control the
code and carrier replica signals for each satellite channel. In
contrast, a conventional tightly coupled GPS/INS system uses
separate tracking loops for each satellite channel, which operate
autonomously. As a result, the UTC desig Platform: |
