Problems solved by technology

Most of the micro-motion analysis data comes from traditional ground-based or space-based radars. These radars are not designed to extract the micro-Doppler effect in the target. On the one hand, their fixed working mode and detection method limit the accuracy of the target Accurate measurement of micro-motion information does not have a dedicated micro-motion

Abstract

The invention relates to a radar micro-Doppler measurement system and method, and the system comprises a radar subsystem and a terminal subsystem. The radar subsystem is electrically connected with the terminal subsystem. The radar subsystem is used for transmitting radar signals, receiving echo signals of the radar signals and carrying out first-stage signal processing on the echo signals to generate target data information; and the terminal subsystem is used for controlling system parameters of the radar subsystem and is also used for carrying out second-stage signal processing on the target data information to complete detection of the micro-motion target so as to obtain micro-Doppler characteristic parameters. According to the radar micro-Doppler measurement system and method, a micro-motion target is sensed by the transmission of the radar signal, so as to achieve the detection of the micro-motion target. The system and method can adapt to a severe working environment, and the micro-Doppler characteristics of the micro-motion target can be measured all the time and all weather.

Description

technical field [0001] The invention relates to the technical field of radar measurement, in particular to a radar micro-Doppler measurement system and method. Background technique [0002] Fretting refers to the small movement or motion component of a target or target component radially relative to the radar. Fretting is ubiquitous in nature, such as the body movement of the human body (the movement of the chest cavity during heartbeat and breathing), the swing of pedestrians' hands and legs, the vibration of bridges and wings, electric motors, crawler tracks, helicopter rotors, and antennas on warships and armored vehicles The rotation of the hood, the pitching and wobbling of the ship, and the flutter (vibration, spin, precession and nutation) of the ballistic missile warhead. The micro-Doppler feature of the micro-moving target reflects the electromagnetic characteristics, geometric structure and motion characteristics of the target, and has the characteristics of targe...
