Abstract

The invention relates to a key index testing system and a method for a low-altitude slow and small target detection radar. The system comprises a target unit and a ground station. The target unit, asa detected target in the radar testing, reflects the radar detection signals; and the target unit establishes a wireless data transmission link with the ground station, and transmits its own positioninformation to the ground station through the data transmission link. The ground station establishes a connection with the radar network, and obtains the detection result of the radar on the target unit through the radar network; and the ground station compares with the position information of the target unit obtained through the data transmission link, and tests the radar ranging accuracy and theangle measurement accuracy. The test cost of the key index testing system and the method for the low-altitude slow and small target detection radar is reduced from 200,000 to 600,000 to 10,000 to 20,000 in the case of same time-consuming as the conventional radar test; the automatic test is supported; and the requirements of millimeter wave continuous wave low speed UAV detection radar can be met.

Description

technical field [0001] The invention relates to the technical field of radar testing, in particular to a key index testing system and method for low-slow and small-detection radar. Background technique [0002] Detailed indicators such as radar distance accuracy and angle accuracy are realized by special radar test equipment (radar signal simulator). During the test, the radar needs to be placed in a microwave anechoic chamber that meets the requirements. The target distance, velocity vector, pitch angle, and horizontal angle are determined by The radar signal simulator generates, compares the parameters of the signal simulator with the radar test results, and evaluates the distance accuracy and angle accuracy indicators. [0003] Currently, most radar test systems are developed for pulsed radars below 18 GHz. For continuous wave radar, there are few development components, the development cost of the signal simulator is high, and the cost of the millimeter-wave anechoic ch...
