Embodiment Construction

[0023] Next, the technical solutions in the embodiments of the present invention will be described in the following examples, and the described embodiments are merely, not all of the embodiments of the present invention. Based on the embodiments of the present invention, those of ordinary skill in the art will belong to the scope of the present invention in all other embodiments obtained without creative labor.

[0024] It should be noted that all directional instructions (such as above, lower, left, right, front, and post, ...) are only used in a particular attitude (as shown in the accompanying drawings). The relative positional relationship, the movement situation, etc., if the specific posture changes, the directional indication is also changed accordingly.

[0025] Further, as described in the present invention, as described in the description of "first", "second", etc., is only used to describe purposes, and cannot be understood as an indication or implies its relative impor...

Abstract

The invention discloses a method for realizing simultaneous transceiving of airborne electronic equipment based on frequency conversion, which utilizes a ground transponder and an airborne transponder to form a double-station synchronous system for performing frequency conversion twice, so that the transceiving frequencies on the same transponder are different, transceiving isolation is realized, and the simultaneous transceiving technology is realized. The ground transponder receives an AGHz radio frequency signal transmitted by a radar, the AGHz radio frequency signal is converted into an intermediate frequency through the receiving down-conversion assembly, an interference signal is generated through the digital assembly, the interference signal is sent to the up-conversion assembly and converted into a BGHz radio frequency interference signal, the interference signal is sent to the solid-state power amplifier for amplification, and the signal is transmitted through the ground transmitting antenna. The airborne receiving antenna receives a BGHz radio frequency signal sent by the ground transponder, the BGHz radio frequency signal is converted into an AGHz radio frequency signal through the airborne receiving frequency conversion assembly, the AGHz radio frequency signal is amplified through the airborne transmitting assembly and sent out through the airborne transmitting antenna, and the interference mode of transmitting and receiving at the same time is completed. And the frequency deviation caused by adopting different local oscillators is reduced by using rubidium clocks for three times of frequency conversion.

Description

Technical field [0001] The present invention belongs to the field of electronic counterfeit, and more particularly to a method based on frequency conversion to realize the transmission and reception of the onboard electronic device. Background technique [0002] The airborne jamming machine uses the simultaneous technique, and when deceptive interference, the coherent accumulation gain of the interference signal can be improved, which can increase the effective interference time, resulting in a better interference effect. The current airborne interference machine generally has problems that are released, that is, the receiving antenna and transmit antenna of the airborne interference machine will generate self-exchanging, which affects the interference performance, which affects the simultaneous interference technique for the transmission and reception. Traditional solutions to the transmission and reception isolation are the interval distance of the transmission and reception an...
