A High Speed Detection Scheme for Point Targets in a Multitarget Environment

The purpose of this paper is to develop a high speed detection scheme for moving and / or stationary point targets in a multitarget environment as registered in an IR image sequence. An iterative approximate 3-D line searching algorithm based upon the geometric representation of lines (for non-maneuvering targets in space) in a 3-D space is derived. The convergency of the algorithm is proved. An analysis is performed of the theoretical detection performance of the algorithm. The statistical experiment results show high effectiveness and computational efficiency of the algorithm in the case of low SNR. The idea may be employed to satisfy the real-time processing requirement of an IR system.

Radar Imaging Based on Iterative Algorithms

It has long been realized that the problem of radar imaging is a special case of image reconstruction in which the data are incomplete and noisy. In other fields, iterative reconstruction algorithms have been used successfully to improve the image quality. This paper studies the application of iterative algorithms in radar imaging. A discrete model is first derived, and the iterative algorithms are then adapted to radar imaging. Although such algorithms are usually time consuming, this paper shows that, if the algorithms are appropriately simplified, it is possible to realize them even in real time. The efficiency of iterative algorithms is shown through computer simulations.     

牡丹与寒梅:以两种花卉阐释唐宋士人的差异

在中国古代,历来有花卉鸟兽抒情明志的传统。在特定历史时期中,某种自然物象同特定的情感和意义之间建立了相对稳固的关系,经过社会的认同,物象便转化为人的情感符号而失去了自身客观性质的特征而成为时代的一种标志。牡丹与寒梅就是唐宋两代士人给予充分观照的审美对象,前者艳绚丽、神采外放,代表了唐代建功立业、开张扬厉的时代精神;后者瞿瘦淡雅,外枯中膏,可与宋人淡泊收敛,质朴深微的心态相契合。唐人爱牡丹,宋人重寒梅,从两种花卉的分析中,可对唐宋的时代精神加以阐释。
