Vehicle-used active anti-collision radar echo simulator

Abstract

The embodiment of the invention discloses a vehicle-used active anti-collision radar echo simulator. A vehicle-used active anti-collision radar signal is subjected to independent two stage frequency conversion through a millimeter wave system and a centimeter wave system, wherein all components of the millimeter wave system are detachable components, thus the components of the millimeter wave system can be configured to be components targeting radar signals of a specific frequency band, so that the vehicle-used active anti-collision radar echo simulator provided by the embodiment of the invention can be used for testing vehicle-used active anti-collision radars of different frequency bands, and the university is increased. Moreover, according to the vehicle-used active anti-collision radar echo simulator provided by the embodiment of the invention, the vehicle-used active anti-collision radar is borne by a controllable turntable, thus simulation of variations of relative motion and relative position between a target and the vehicle-used active anti-collision radar can be achieved by changing directions of the vehicle-used active anti-collision radar, the design complexity of the vehicle-used active anti-collision radar echo simulator is simplified, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of automotive radar, and more specifically relates to a vehicle active collision avoidance radar echo simulator. Background technique [0002] With the rapid development of highway networks in various countries, vicious traffic accidents continue to increase. In order to reduce accidents, protective measures such as driving seat belts and airbags have been adopted successively. However, these technologies are all passive protection and cannot fundamentally solve the problem. Vehicle active collision avoidance radar has become a hot spot in international research and development in recent years. [0003] In order to meet the requirements of the networking and layout verification of the vehicle system, it is necessary to conduct hardware-in-the-loop testing of the vehicle active collision avoidance radar through the echo simulator to verify the function of the vehicle active collision avoidance radar, and th...
