Abstract

The invention discloses an automatic testing system and an automatic testing method for the non-contact transmission characteristics of a millimeter waveband. The method comprises the following steps of: initializing the automatic testing system for the non-contact transmission characteristics of the millimeter waveband; calibrating the automatic testing system for the non-contact transmission characteristics of the millimeter waveband, and finishing a spatial transmission characteristic test under the condition of no element to be tested to obtain test information in a calibration state; finishing a transmission characteristic test under the condition that the element to be tested exists to obtain test information in a test state; obtaining the corresponding power information of a transmitter and a receiver under each frequency value; and subtracting power information obtained in the calibration state from power information obtained in the test state, and displaying a test curve of the transmission characteristics of the element to be tested. By the system and the method, a test in transmission characteristic parameters of 76 to 77GHz can be realized automatically, the problem of absence of millimeter wave testing means and testing equipment is solved, and the shortcomings of high cost, large volume, difficulties in automatic control and the like of testing equipment are overcome.

Description

technical field

[0001] The invention belongs to the technical field of testing and measuring of solid-state electronics, and relates to an automatic testing system and testing method of millimeter-wave band non-contact transmission characteristics. Background technique

[0002] With the gradual development of the traditional traffic mode in the direction of intelligence, safety, energy saving, and high efficiency, the 77GHz ACC (Adaptive Cruise Control, Adaptive Cruise Control) system can realize that vehicles can drive freely on the road by their own intelligence, and roads rely on their own intelligence to drive freely on the road. Adjust the traffic flow to the best state; with the help of this system, managers will have a clear grasp of the whereabouts of roads and vehicles. The ACC system on the new BMW 7 series has been transplanted to the new BMW 5 series. This system has a different control program from the traditional cruise system. Through the control handle under ...
