The polarimetric information in the target scattering signal has great potential on target detection , enhancement , filtering and recognition . some novel techniques can be proffered for detecting concealed targets , weakening the influences of adverse em environments , confronting active jamming and recognizing targets . basic theory of radar polarization is studied firstly 雷达目标散射信号中的极化信息在目标检测、增强、滤波及识别中有着巨大的应用潜力,为雷达系统在反隐身、削弱恶劣电磁环境的影响、对抗有源干扰和识别目标等方面提供了新的技术途径。
Higher capabilities were put forward for detection , identification and anti - interference of torpedo in future naval battle . compared with the narrow - band processing , wide - band processing is a new direction for underwater signal processing for its advantages including abundant information of wide - band echo and little correlation of reverberation 未来海战对鱼雷在探测目标、识别目标和反对抗能力方面提出了更高的要求，而宽频带回波信号具有携带目标信息量大，混响背景相关性弱，利于检测、识别目标等优点，因此自导系统发展的方向是宽频带自导。
( 4 ) identify the railway passengers " current needs accurately and precisely through the research on consumer behavior which helps to forecast their potential needs , understand those target consumers better , and position , segment the market in a scientific way . provide the consulting service in the view of consumer psychology for east china railway enterprise ' s marketing strategy and tactics 通过消费者特征的研究，更精细和准确地识别消费者的现实需求，预测消费者的潜在需求，更好地识别目标消费者，科学地进行目标市场定位和细分市场，为市场营销策略的制定提供消费心理学的咨询与指导。
In waveform design aspect the impulse response elimination method is presented to detect and discriminate the targets . in the signature waveform detection aspect the target ' s late - time response is adopted as the signature waveform , then the adaptive beam formation arithmetic is used to detect this signature waveform 在发射波形设计中提出了冲击响应消去法，设计与目标匹配的发射波形来检测和识别目标；在特征波形检测中提出用目标冲击响应的晚期响应作为目标的特征波形，再利用自适应波束形成的算法来检测待测目标的特征波形。
The results of recognition illuminates that this model can efficiently improve the recognition rate ( and the time of recognition for only using well - bp neural network is too long , but that of combing the simple - bp neural network with bayes method is not so long for target identification when the two methods have the same recognition rate . ) 识别结果表明，这种方法能够有效地提高识别率。同样的，将bp神经网络与d - s方法相结合( bpd - s方法)来识别目标，其识别率有了进一步的提升，其稳健性相对较好，但是识别时间比bpbayes方法的要长。
