Abstract

The invention relates to a short-range radar system and a target measurement method based on the system. The system comprises a signal generator used for generating emission signals, a transmitting antenna used for transmitting the emission signals, a first receiving antenna and a second receiving antenna which are used for receiving received signals, a first receiver and a second receiver which are used for demodulating the received signals and both generating one path of I signals and one path of Q signals for a signal processor, the signal processor used for processing the I signals and the Q signals to generate target parameters, sending the target parameters to a background computer and performing time sequence control on the signal generator, and the background computer used for processing the target parameters to obtain a target measurement result. Each receiving antenna adopts a double-channel receiving mode, so that the two receiving antennas can form two paths of Q signals and I signals, and therefore, the distance and angle of a target can be accurately measured. The short-range radar system has the advantages of simple structure and low cost.

Description

technical field [0001] The invention relates to the technical field of radar, in particular to a short-range ranging radar system and a target measurement method based on the system. Background technique [0002] The short-range ranging radar system not only requires high ranging accuracy, but also requires high-precision measurement of target angles, and it is aimed at multiple targets. At present, radars with large bandwidth systems are generally used to achieve high-precision ranging, but radars with large bandwidth systems cannot achieve high-precision measurement of target angles, and the systems are complex and costly. Contents of the invention [0003] The object of the present invention is to provide a short-range ranging radar system capable of simultaneously measuring target distance and angle with high precision and a target measuring method based on the system, and the radar system is simple and low in cost. [0004] In order to achieve the purpose of the abov...
