Problems solved by technology

This method requires personnel to repeatedly enter the test darkroom and adjust the position of the corner reflector, which is easy to damage the electromagnetic environment inside the darkroom, and the efficiency is low. It is not suitable for the quality test of the product on the production line.
In addition, the angle coverage of the traditional angular resolution test system is not large, and the general guide rail coverage angle is only 5-10 degrees, which is difficult to meet the wide-angle test requirements

Abstract

The invention provides a radar angular resolution test system. The radar angular resolution test system comprises a detection robot used for carrying a radar to be tested to carry out space displacing, an arc guide rail and two corner reflector devices which are both mounted on the arc guide rail and controlled to move along the arc guide rail, the corner reflector devices are provided with cornerreflector assemblies capable of generating an echo signal which can be fed to the radar to be tested when a radar signal is received, according to the radar angular resolution test system, the detection robot is arranged to carry the radar to be tested to carry out space moving, the large-angle guide rail is arranged, the included angle at any angle can be formed between the two corner reflectordevices and the radar to be tested, and the wide-angle radiator resolution test needs can be met.

Description

technical field [0001] The invention relates to the technical field of radar detection, in particular to a radar angular resolution testing system. Background technique [0002] Cars are an important means of transportation and means of transportation in the industrial age. With the increase in the number of cars in the early years, the congestion of the road environment, and a large number of people becoming drivers, traffic accidents occur frequently, causing heavy economic losses and casualties. The car assisted driving system can perceive targets, pedestrians and obstacles, and take defensive measures, and has the ability to prevent most traffic accidents. Automobile radar is the core equipment of automobile assisted driving system. Radar is a high-precision device that detects and extracts information from specific targets within a certain range. The radar radiates electromagnetic waves to the surroundings, and then receives the reflected echo of the target by itself,...
