Embodiment Construction

[0030] In the present invention, the transmitting and receiving antenna placed on the vertical plane in the arch method is changed to be placed on the horizontal plane, and the transmitting and receiving antennas are respectively placed on two independent single-axis turntables, and the two turntables move in opposite directions on the arc guide rails on the ground. The tested panel is installed on the fixed bracket. During the test, the tested panel is still. The electric axis of the transmitting and receiving antenna always points to the center of the tested panel. The reflection angle is equal to the incident angle. The test device is as follows: figure 2 , image 3 shown. For this test method, a darkroom not less than 8m*8m*4m can complete the power reflection test of the equivalent flat panel.

[0031] In the specific implementation process, two single-axis turntables are used for power reflection testing. Both turntables move at the same speed but in opposite directio...

Abstract

The invention belongs to the technical field of microwave measurement, and particularly relates to test equipment and a test method for equivalent flat plate power reflection. The test equipment comprises a test instrument, a microwave anechoic chamber, an arc guide rail, rotary tables, test antennas and a tested piece, wherein the test instrument, the arc guide rail, the rotary tables, the test antenna and the tested piece are installed in the microwave anechoic chamber; the two rotary tables are symmetrically installed on the arc guide rail, the test antennas are installed on the rotary tables, the center of the tested piece is located on the axis where the circle center of the arc guide rail is located, the test instrument is connected with the two test antennas through the radio frequency cable, and the extension lines of the axes of the two test antennas intersect on the axis of the circle center of the arc guide rail. The test equipment provided by the invention can effectively save the volume of the microwave anechoic chamber, and the equivalent flat plate power reflection test method can effectively improve the test efficiency.

Description

technical field [0001] The invention belongs to the technical field of microwave measurement, and in particular relates to a test device and a test method for equivalent flat panel power reflection. Background technique [0002] The equivalent plate is an indispensable test sample in the development process of the radome, and the electrical properties of the equivalent plate can reflect the main electrical properties of the radome. In order to reduce the technical risk in the development of the radome, an equivalent flat panel is usually manufactured and tested for electrical performance at the initial stage of development, and the correctness of the design results of the electrical performance of the radome is judged according to the test results. [0003] The main test parameters of the equivalent panel include power transfer efficiency, power reflection and insertion phase delay. At present, the equivalent flat plate power reflection measurement mainly refers to 5.3 of G...
