在无线通信中使用跳频技术是军事通信中最主要的抗干扰手段之一, 而如果系统中能使用合适的中心频率可以快速跟踪跳频变化的带通滤波器将可以明显改善系统的抗干扰性能。文中从实际应用出发, 比较了几种可用于实现带通滤波器快速变频的方案, 选择了简单、实用的开关电容阵改变带通滤波器中心频率的方案(The use of frequency hopping in wireless communication technology is the most important anti-jamming in military communications, one of the means, and if the system can use the appropriate center frequency can be fast-tracked changes in frequency-hopping band-pass filter will be able to significantly improve the system anti-jamming性能. This paper from the actual application, the comparison of several band-pass filter can be used to achieve the rapid conversion of the program, choose a simple, practical switched capacitor array to change the center frequency of band-pass filter program)

介绍了经典的时频分布和检测理论的同时，作者利用时频分布的方法，将一 维时间信号转化到二维的时频空间中，通过提取图像的特征来判决信号和杂波， 采用的数据是使用McMaster IPIX雷达，在加拿大东海岸附近测得的。实测数据 研究表明此方法可以得到很好的检测结果。 (In this paper,we first review the time-frequency analysis and time -frequency-based detection methods.Secondly,by analyzing a mass of the measured data of sea clutter,we show the difference of time-frequency geometric features between echoes with a target and pure sea clutter.Finally,we given the detection algorithm based on the time-frequency geometric features.The results of the measured data show that the proposed method can effectively find low-velocity small targets in sea clutter.This approach is a novel try to detect small targets in sea clutter.)
