AI Technical Summary

Technical Problem

When measuring target position information, existing radar systems need to set up multiple channels and network support, resulting in a large consumption of hardware resources.

Method used

A radar antenna measurement system is designed, including multiple radar antenna subarrays, wave controllers, synthesizers, signal receiving channels and processors. The echo signal is phased through the wave controller, the synthesizer performs signal synthesis processing, the signal receiving channel is analog-to-digital conversion, and the processor measures the target position information.

Benefits of technology

The system can effectively save hardware resources, reduce system volume, and can independently measure the distance information, speed information, pitch angle and azimuth angle of the target.

Abstract

The invention relates to the technical field of radar measurement, and discloses a radar antenna measurement system, which comprises a radar antenna subarray, a wave controller, a synthesizer, a signal receiving channel and a processor, and is characterized in that the radar antenna subarray is used for transmitting an electromagnetic wave detection signal to a target and receiving a first echo signal reflected by the target; the wave controller is used for performing phase change processing on the phase of part of the first echo signal to obtain a processed echo signal; the radar antenna subarray is also used for transmitting the processed echo signal and the echo signal which is not processed by the wave controller in the first echo signal to the synthesizer; the synthesizer is used for synthesizing the received echo signal to obtain a second echo signal and transmitting the second echo signal to the signal receiving channel; the signal receiving channel is used for performing analog-to-digital conversion processing on the second echo signal to obtain a first digital echo signal and transmitting the first digital echo signal to the processor; the processor is used for measuring and determining position information of the target according to the first digital echo signal. According to the invention, hardware resources of the radar system are saved.
