Method and device for simulating aircraft RCS by using target aircraft RCS

Abstract

The invention relates to a method and device for simulating an aircraft RCS by using a target aircraft RCS. The method comprises the steps: obtaining an RCS curve of an aircraft; acquiring an RCS curve of the target drone; setting the target drone to change the RCS curve of the target drone so as to enable the RCS curve of the target drone to accord with the RCS curve of the aircraft, extracting the corrected RCS curve of the preset position, comparing the corrected RCS curve with the RCS curve of the aircraft, and calculating an error; and determining the setting of the target drone accordingto the error range. The RCS of the target drone is changed by loading the Luneberg lens reflector to the target drone, so that the RCS is close to a real airplane, meanwhile, the influence of the Luneberg lens reflector on the aerodynamic characteristics of the target drone is considered and analyzed, and the enhanced amplitude and angle range of the RCS of the target drone can be controlled by changing the loading position and mode of the Luneberg lens reflector. The RCS of the RCS of the target drone in a specific angle range is enhanced to 10dB; and the purpose of simulating the real aircraft RCS by using the target aircraft RCS is achieved.

Description

Technical field [0001] The invention belongs to the technical field of electromagnetic fields and microwaves, and specifically relates to a method and a device for simulating the RCS of an airplane by using the RCS of a target drone. Background technique [0002] Radar Cross Section (RCS) is a physical quantity that measures the ability of a target to scatter radar waves. It is defined as: 4π times the ratio of the power scattered from the target in the receiving direction to the power density of the plane wave incident from a given direction in a unit solid angle. The larger the radar cross-sectional area, the farther the radar can find. Stealth aircraft is trying to reduce the cross-sectional area of ​​the radar to reduce the radar's detection range to achieve "stealth". On the other hand, the target used to simulate the real drone RCS is called a fake target. The false target is usually an aerial target. However, the RCS of the target is limited by its material and shape, a...
