Automatic radar T/R (Transmitter/Receiver) assembly testing system and method thereof

Abstract

The invention discloses an automatic radar T / R (Transmitter / Receiver) assembly testing system and a method thereof. The main idea is: a radar T / R testing hardware platform is built, a vector network analyzer is initialized, an address, a parameter flag bit, a clock state, a channel label, a phase shifter state, a starting frequency, a stopping frequency, a scanning point number, a general testing state number, a storage file title character string, a parameter name character string, a file name character string and a file storage path character string are set, a port transmission coefficient is further built on the vector network analyzer, and a parallel port control clock of the radar T / R assembly is loaded; and then, phase data, gain data and standing-wave ratio data of the radar T / R assembly in a phase shifting state and in a degradation state are acquired respectively, the data are then processed, and the standing-wave ratio, 0-state phase, 0-state degradation, 0-state consistency phase and phase shifting precision of the radar T / R assembly in the phase shifting state and in the degradation state at a frequency point are acquired respectively, and storage by an automatic storage module is then carried out.

Description

technical field [0001] The invention belongs to the technical field of radar, in particular to a radar T / R component automatic test system and its method, that is, a radar transmitter / receiver (Transmitter and Receiver) component automatic test system and its method, suitable for active phased array Automated testing of radar T / R components. Background technique [0002] At present, active phased array radar is in the mainstream trend of radar research and development in the world today. In terms of airborne, the active phased array radar can not only obtain the position information of the target (including distance, azimuth, and pitch angle), but also obtain the speed and shape information of the target, guide the missile to attack the target, and directly determine the position of the target. Combat performance of a fighter jet. A typical phased array radar uses a phase shifter to simultaneously control the transmission and reception of the radar antenna beam. Each antenn...

Problems solved by technology

However, in a general sense, a radar has hundreds or even thousands of radar T / R components, which makes the test task very large, and even makes it almost impossible to complete the test task manually
