Abstract

The present invention provides a broadband RCS test method based on multi-channel simultaneous testing, which fully utilizes the four channels of a four-port vector network analyzer to simultaneously test the ability of four different frequency band signals, by placing 4 groups of antennas of different frequency bands side by side, And the port of the transmitting and receiving antenna is directly connected with the transmitting and receiving port of the vector network analyzer, and the main control computer system coordinates and controls through the bus such as LAN or GPIB. Using the above scheme, by giving full play to the ability of simultaneous testing of multiple ports of the instrument, combined with corresponding software processing, multiple frequency bands can be tested at the same time, which can effectively solve the problem of low efficiency of traditional RCS testing.

Description

technical field [0001] The invention belongs to the technical field of wideband RCS testing of multi-channel simultaneous testing, and in particular relates to a wide-band RCS testing method based on multi-channel simultaneous testing. Background technique [0002] The radar cross section (RCS) characteristic of a target is usually a broadband index, so it is necessary to test the RCS value of the target in a wide frequency range. [0003] For the RCS characteristic test of the target, from the perspective of the hardware system, its functional block diagram is as follows figure 1 As shown, it is mainly composed of a main control computer 10, a vector network analyzer 12, a test turntable 18 and its turntable controller 11, a receiving antenna 15, a transmitting antenna 14, a transceiver antenna support 13 and a low scattering support 17. Coordinate and cooperate to complete the test work together. Taking the far-field test as an example to introduce the specific test proc...
