A pivotal problem to recognize of the precise position of laser facula has been solved in the process of design work: Firstly the method of background-subtraction is used to eliminate or weaken the affect of background light. Secondly the image threshold segmentation operation and morphologic operation are used to locate the sketchy position of laser facula ; Then the new method of Extracting Edge are designed based on character of laser facula , by using this method in the search area the edges of laser facula can be extracted effectively; At last the optimum picture of laser facular is selected by using the triggering function of hardware and function of software. The exact result can be obtained only by image processing to optimum picture.

To solve the exsisting problems in the realization of the LFM/CW radar, the thesis presents a technique for dynamically measuring the LFM/CW signals, which can accomplish the dynamic measurements of FM linearity, FM bandwidth and FM slop of the transmitted signals of LFM/CW radars. This technique creates an effective and accurate means of judging the performance of LFMCW radars. The linearity-correction techniques presented in the thesis successfully make the linearity of the transmitted signals of an actual LFM/CW radar reduce from approximately 25% to 0. 1%(or r. m. s linearity of 0.04%), better than the best results (0.22%) obtained by foreign researchers with complex linearization closed-loop in the same kind of LFM/CW radars, according to the published literatures during the last decade. In order to improve the capability of the real-time processing and range-cells management of LFM/CW radars, the principle of equivalent mixing by lacking-sampling process of band-pass real signals is proposed based on the well-proved improvedversion of sampling theorem of band-pass real signals. This principle is used to configure the range-segments processing of the beat signals of an actual LFM/CW radar. The techniques of system-background interference suppression and the beat signal's dynamic range suppression are proposed, and are realized in an actual LFM/CW radar to demonstrate their effectiveness.
