Embodiment Construction

[0029]In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] attached figure 1 A schematic diagram of the operation of the multi-probe quasi-far-field electromagnetic scattering cross section (RCS) extrapolation test system provided by the present invention. The system is equipped with a special test radar multi-probe group at a distance of radius R from the center of the turntable, and each probe group includes a transmitting probe TX and a receiving probe RX. The target to be measured is placed in the center of the turntable, and the one-dimensional rotation of the target to be measured can be realized by controlling the rotation of the ...

Abstract

The invention discloses a multi-probe quasi-far-field electromagnetic scattering cross section (RCS) extrapolation test system. The system is composed of a quasi-far-field electromagnetic scattering measurement system and a quasi-far-field electromagnetic scattering measurement data processing system. The first part realizes one-dimensional rotation of a target to be tested by controlling a turntable, and acquires an original signal required for quasi-far-field electromagnetic scattering measurement of the target to be tested by using a special test radar multi-probe circuit. The second part realizes acquisition of electromagnetic scattering data, and calculates a far-field horizontal plane RCS of the target to be tested according to a quasi-far-field-far-field transformation extrapolationalgorithm. The test system provided by the invention overcomes the limitation of the traditional electromagnetic scattering test means on the test distance and the size of the measurable target, reduces the influence of physical sizes among multiple probes, and has the advantages of high test efficiency and low cost.

Description

technical field [0001] The invention relates to the fields of radar electromagnetic scattering cross section (RCS) measurement of aircraft and radar target characteristic signal testing, in particular to a multi-probe based quasi-far-field electromagnetic scattering cross section (RCS) extrapolation testing system. Background technique [0002] Electromagnetic scattering measurement is mainly used to measure the scattering characteristics of the target, and the scattering characteristics of the target are usually measured by radar cross section (RCS). Since the invention of radar in World War II, military and civilian radars have developed rapidly, such as terrain collision avoidance in navigation systems, air traffic control, and weather warnings, and many civilian radar systems have emerged. Military equipment such as aircraft, ships and The radar system above the satellite plays the role of detection, surveillance and attack. With the rapid development of radar, various ...
