关联成像与传统的成像不同,是光学成像领域中一种新的成像体制,实现了探测与成像的分离。关联成像在雷达成像中拥有广阔的应用前景,为雷达成像的发展提供了新的思路。阐述了实现雷达关联成像中随机辐射场的几种方法,并重点分析其中一种模型。通过改变模型参数,分析了辐射场的变化趋势,研究了信号带宽和目标散射点间距对图像分辨率的影响,研究结果对雷达关联成像系统参数的设置具有一定的参考作用。
Unlike traditional imaging, associated imaging is a new imaging system in the field of optical imaging, which realizes the separation of detection and imaging. Associative imaging has broad application prospects in radar imaging and provides a new idea for the development of radar imaging. Several methods for realizing stochastic radiation field in radar-related imaging are described, and one of the models is analyzed emphatically. By changing the parameters of the model, the change trend of the radiation field is analyzed. The influence of the signal bandwidth and the distance of the target scattering point on the resolution of the image is studied. The research results are of certain reference for setting the parameters of the radar associated imaging system.
