Single antenna ultra wide band radar system for imaging applications

Abstract

The invention relates to a single-antenna ultra-wideband radar system for imaging application, and the system comprises a signal transmitting and receiving module which is used for transmitting an electromagnetic wave signal to a to-be-detected region at a preset transmitting angle, receiving a feedback signal reflected by an electromagnetic wave through the to-be-detected region, and recording the time of receiving the feedback signal at each position; the imaging module draws image information of the to-be-detected area according to the time when the feedback signals are received at all the positions, and a pre-drawn image is formed; the extraction module is used for extracting historical data of the to-be-detected area, and the historical data comprises plate movement information of the terrain and crustal movement with the severity of more than three levels in one year of the to-be-detected area; and the correction module is used for correcting the distance information in the image information according to the historical data to form an optimized image. Through the optimization of the pre-drawn image, the optimized image finally displayed by the display module has greater practical guiding significance, and the accuracy of image acquisition is improved.

Description

technical field [0001] The invention relates to the technical field of radar imaging, in particular to a single-antenna ultra-wideband radar system for imaging applications. Background technique [0002] The research on imaging radar technology in the world is relatively early, and it has been applied in systems such as robot automatic navigation and target recognition. In recent years, some enterprises in our country have also begun to conduct research in this area, and have applied it to various fields, especially for fields that require high precision. [0003] The working principle of the imaging radar system is based on scanning the target scene with a light beam, receiving the light radiation reflected by the scene, generating continuous analog signals, and restoring it to a real-time image of the target scene. It is crucial for the restoration of the target scene. [0004] However, when the existing imaging radar system restores the target scene, the image of the ta...
