Technical Field
The invention relates to the field of radar measurement and control, in particular to a civil millimeter wave radar multi-antenna measurement and control system based on three-dimensional space scanning.
Background
When the target approaches the radar antenna, the reflected signal frequency will be higher than the transmitter frequency; conversely, when the target moves away from the antenna, the frequency of the reflected signal will be lower than the transmission probability, and the frequency change caused by the doppler effect, called doppler shift, is proportional to the relative velocity V and inversely proportional to the frequency of the vibration. Thus, by detecting this frequency difference, the moving speed of the target relative to the radar, that is, the relative speed of the target and the radar can be measured. According to the time difference between the pulse transmission and the pulse reception, the distance of the target can be measured, but the existing system is low in equipment precision, not wide in applicability and high in measurement and control cost.
