Abstract

The invention discloses a general extensible radar automatic test system which comprises a CPCI test host (1), a programmable power supply (2), a display control terminal (3), a composite target simulator (4), a power meter (5), a spectrometer (6), an oscilloscope (7), a switch network (8), a signal generator (9), a network switch (10), a radar front-end test module, an information processor test module, and a radar whole-machine test module. The test system makes a radar go into a working state, and provides an external excitation signal. Then, the system analyzes and judges an output signal of the radar and determines whether the radar works properly so as to complete radar test. Through dada transmission via a network, the speed of data transmission is improved greatly, and a large amount of data generated by radar can be stored and processed quickly. Because of the use of a CPCI bus, the size of equipment is reduced, and the radar automatic test system is easy to carry and transport.

Description

technical field [0001] The invention relates to a radar automatic test system based on network, in particular to a universal and expandable radar automatic test system. Background technique [0002] At present, with the continuous improvement of radar technology, the internal structure of radar is becoming more and more complex. The coexistence of analog circuits and digital circuits, high-frequency signals and low-frequency signals in the system brings great challenges to the generalization and miniaturization design of radar test systems. [0003] The current radar test system is mainly composed of a test host and a general-purpose test instrument. The general-purpose instrument is mainly controlled remotely through the GPIB bus, but the transmission speed of the GPIB bus is slow, which is not conducive to the test of radar high-speed signals; The metal chassis structure greatly restricts the portable design. In addition, the test host currently mainly uses Windows as the...
