Abstract

The invention relates to a key index testing system and method for low-slow and small detection radar. The system includes a target unit and a ground station; the target unit is used as a detected target during radar testing, and reflects the detection signal of the radar; and is connected with the ground station Establish a wireless data transmission link, and send its own position information to the ground station through the data transmission link; the ground station establishes a connection with the radar network, and obtains the detection results of the radar to the target unit through the radar network; The position information of the target unit itself is compared, and the ranging accuracy and angle measuring accuracy of the radar are tested. The present invention reduces the test cost from 200,000 to 600,000 to 10,000 to 20,000 in the same time-consuming test as the traditional radar test; and supports automatic testing; it can meet the requirements of millimeter wave continuous wave low-speed unmanned aircraft detection radar requirements.

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...
