基于RCS静态宽带数据的雷达目标成像算法

Radar target imaging algorithm based on RCS static broadband data

利用宽带雷达目标电磁散射特性数据可以实现雷达目标的一维距离像,在二维像实现过程中,传统做法需要利用雷达目标电磁回波的多普勒频率以实现雷达目标的方位像。探讨了基于宽带雷达散射截面(RCS)静态数据(没有多普勒频率)的二维成像算法,突破了传统需要多普勒频移数据才能实现二维雷达像的限制。最后探讨了调整成像算法若干参数的不同成像效果。本文工作以期能够为不同雷达成像应用场景提供技术及理论支撑。

One-dimensional range profile of radar target can be realized by using wide band electromagnetic scattering characteristic data of radar target. In the process of realizing two-dimensional imaging algorithm, the Doppler frequency is required traditionally for azimuth imaging. In this paper, a twodimensional imaging algorithm based on wideband Radar Cross Section(RCS) static data(without Doppler frequency) is discussed, which breaks through the traditional limitation that Doppler frequency shift data is necessary to realize two-dimensional radar imaging. Finally, several different parameters of imaging algorithm are adjusted for realizing different imaging effects. This work is expected to provide the technical and theoretical supports for different radar imaging application scenarios.
