Abstract

A ZYNQ-based portable radar testing system and testing method relate to the field of radar testing. The invention aims to solve the problems of poor real-time compatibility and communication processing of the existing radar test system. The serial communication module is used to receive the GPS data sent by the GPS device and the inertial navigation data sent by the inertial navigation device, transmit the data to the main control module, and also transmit the A frame data sent by the main control module to the radar under test , and receive the B-frame data returned by the radar under test, and transmit the data to the main control module; it is also used to receive the periodic pulse generated by the main control module, and send it to the radar under test, and receive the telemetry data returned by the radar under test; the main control The module is used to receive GPS data and inertial navigation data, respectively solve them into A-frame data or simulate A-frame data, and send out A-frame data after the set periodic pulse arrives, and is also used to generate periodic pulses. Used to receive B-frame data and telemetry data. It is used for radar testing.

Description

technical field [0001] The invention relates to a ZYNQ-based portable radar testing system and testing method. It belongs to the field of radar testing. Background technique [0002] The content and scope of radar testing are very extensive. Since the development of radar testing system, its development process has gone through manual testing, automatic testing, and the current general testing stage. The generalized module design method has gradually become the mainstream. [0003] Radar real-time communication processing is one of the important means to realize radar testing. It runs through the whole process of radar from development to delivery to final retirement. Important means are of great significance to ensure the rationality of the radar design and ensure the function realization of the radar and its system. [0004] In order to meet the requirements of serial communication, data calculation and data storage in the radar test process, the radar test system mostly...
