Abstract

The invention provides an echo signal simulation method, a system as well as an echo signal simulator. The method is applied to an echo signal simulator comprising groups of hardware processing chips. The method is performed through the following steps: obtaining the working information of a radar, preset fraudulent model information and electromagnetic waves sent by the radar according to the working information of the radar; using the working information of the radar and the preset fraudulent model information, and calculating fraudulent scattering information corresponding to the preset fraudulent model; calculating the modulation information of a plurality of scattering dots by the groups of hardware processing chips according to the working information of the radar, the fraudulent scattering information and the set of scattering dots' positions; calculating intermediate frequency echo signals based on the set of modulation information and electromagnetic wave digital information; and carrying out upconversion to the intermediate frequency echo signals so as to obtain fraudulent interfering echo signals. According to the invention, it is possible to simulate fraudulent interfering echo signals in a large scenario in real time, therefore raising experiment efficiency.

Description

technical field [0001] The present application relates to the field of radar technology, in particular to an echo signal simulation method and system, and an echo signal simulator. Background technique [0002] With the continuous advancement of science and technology, modern science and technology have been applied in the field of militarization. In militarized electronic warfare, imaging radar is widely used because it can identify the position of objects and image objects, such as synthetic aperture radar. In order to prevent one's own target objects from being scanned by the enemy's imaging radar, radar deception technology has been derived. [0003] The main idea of ​​radar deception technology is to install a jamming device on the target object. After receiving the electromagnetic wave emitted by the radar, the jamming device can feed back the deceptive jamming echo signal to the radar. Spoofing jamming echo signals can mislead the radar or prevent the radar from ide...
