Research on High-Resolution Range Profile of Composite Targets in complex environment in Terahertz Band

In this paper, the advantages of terahertz band detection and recognition, combined with high frequency calculation method, are used to achieve High-Resolution Range Profile(HRRP) of composite targets in different environment. And electromagnetic scattering characteristics of composite targets are analyzed. The results show that HRRP can effectively represent shape and structure information of targets and other objects distribution on the ground. Scattering characteristics of composite targets in complex environment and imaging research is of great significance in military applications, such as detecting and identifying military targets hidden in forest vegetation. It is necessary to model composite targets in different environment and recognize targets information through simulation and imaging. The research results provide technical means and data support for targets in different ground echo detection and feature recognition.
