Description

technical field [0001] The invention relates to ultra-wideband, target detection, FPGA, and imaging systems. Specifically, it involves an FPGA imaging system for ultra-wideband microwave target detection. Background technique [0002] A number of research progresses have been made in the field of UWB (ultra-wideband) target detection in the world. UWB target detection is widely used. There are many advantages such as low cost of detection equipment, small equipment size, and no radiation damage to the human body. With the deepening of research on target detection methods, detection experiments have been gradually carried out, and how to image the detection results has become an urgent problem to be solved. The method commonly used by various research teams today is to use workstations to run imaging programs, and use object-oriented languages ​​such as MATLAB language, C language, C++ language, etc. to perform imaging operations on received signals. But using an object-or...
