包括基於多項相位變換的lfmcw雷達速度和加速度估計方法;基於修正多項相位變換的多目標lfmcw雷達速度和加速度估計方法;基於一般高斯噪聲環境下的lfmcw雷達速度和加速度聯合估計方法;另外提出了基於頻域增采樣內插方法以提高lfmcw雷達測距精度。 -
But its detection performance is not so good under multiple targets situation. the mgo - cfar detector ' s detection performance degrades dramatically when there is one interfering target in the reference window
但在多目標環境中的檢測性能較差，當參考滑窗中有一個干擾目標時， mgo - cfar的檢測能力就已經嚴重下降。 -
It gives assistance to improve efficiency of the multiple frames accumulation. by analyzing the merits and demerits of several kinds of preprocessing, such as highpass filtering, median filtering, tophat transformation in mathematical morphology and wiener filtering, the local singularity filtering based on improved susan principle has been given, and it has a high power to raise the probability of target detection in single frame
良好的預處理將提高后續的多幀積累的效率，對比常用的幾種預處理演算法，如高通濾波、中值濾波、數學形態學的tophat濾波、維納濾波等方法的優點和不足，提出了一種改進的susan濾波器? ?區域奇異性濾波，該濾波方法對于提高單幀檢測概率有很好的功效。 -
The various performance of the mosos - cfar detector was analyzed. the result shows that the mosos - cfar detector has good performance under the homogenous background, almost the same as that of the mgo - cfar detector ; good performance against clutter edge, excellent performance under multiple targets situation, the detector ' s detection performance dropped not much when the interfering target is less than r - k1 - k2
計算分析了mosos - cfar檢測器的各種性能，分析表明， mosos - cfar檢測器在均勻背景雜波中的檢測性能良好，和mgo - cfar檢測器的檢測性能相近；抗雜波邊緣能力良好，但是略差於mgo - cfar檢測器；在多目標環境中的檢測性能優秀，當干擾目標數少於r - k1 - k2時，檢測器的檢測性能下降很少。
