Abstract

The invention is applicable to the technical field of radars and provides with a millimeter wave 3D radar system and signal processing flow. The millimeter wave 3D radar system comprises a signal source, an emission signal source power dividing network, a receiving signal source power dividing network, a control module, an array radio frequency front end and a digital rear end. The millimeter wave3D radar system has the advantages that the millimeter wave 3D radar system is designed by using the time division multiplexing-multiple-input-multiple-output technology and the two-dimensional planar thinned array technology, three-dimensional detection can be performed on fixed targets, low-speed targets and the like in a complex environment can be achieved, and the hardware complexity and costof the radar system are lowered greatly.

Description

technical field [0001] The invention belongs to the technical field of radar, and in particular relates to a millimeter-wave 3D radar system and a signal processing flow. Background technique [0002] In recent years, with the rapid development of autonomous driving technology, sensor systems applied to the measurement and perception of the surrounding environment of vehicles have also developed rapidly, among which video systems, lidar and millimeter-wave radar are the main representatives. Compared with video systems and lidar, millimeter-wave radar has better environmental adaptability and lower installation and use costs, so it is also widely used in automotive assisted driving and automotive safety protection applications. [0003] However, the existing millimeter-wave radar products still have serious deficiencies when dealing with complex environments, especially when the car is driving in complex environments such as suburbs, urban areas, and markets (where there are...
