Abstract

The invention relates to a terahertz radar detection system based on a Zynq platform and a method thereof. The system comprises a terahertz transmitting and receiving device, a Zynq processing platform, a control system, an upper computer and a two-dimensional motor. The terahertz transmitting and receiving device is in communication connection with the input end of the Zynq processing platform; the output end of the Zynq processing platform is in communication connection with the input end of the control system and the upper computer; and the output end of the control system is in communication connection with the control two-dimensional motor and the terahertz transmitting and receiving device. According to the terahertz multi-channel radar detection system based on the Zynq platform and the method thereof, the frequency synthesis and modulation waveform generation assembly is controlled by the control system, linear frequency modulation signals of continuous waves, narrow bands and wide bands are generated according to different detection modes, the Zynq processing platform serves as a core processing unit, so that the functions of multi-channel intermediate frequency echo data processing, self-calibration, target searching, high-resolution imaging and the like can be realized.

Description

technical field [0001] The invention relates to the field of terahertz radar detection, in particular to a terahertz radar detection system and method based on a Zynq platform. Background technique [0002] Compared with microwave radar, terahertz radar has a shorter wavelength and has unique advantages such as wide bandwidth, high resolution, Doppler sensitivity, and anti-interference. The high spatial resolution and large bandwidth of terahertz radar are conducive to target imaging and acquisition of target feature structure details, so as to perform more accurate contour recognition on targets. At present, there are many public applications of terahertz high-resolution imaging in anti-terrorism and security checks (such as the detection of hidden objects), and there are few applications of terahertz high-resolution imaging for fine-tuning and multi-dimensional imaging of long-distance moving targets. [0003] The existing terahertz high-resolution detection system has a ...
