Embodiment Construction

[0066] The practical effect of the present invention will be supplemented below with reference to the accompanying drawings.

[0067] simulation one

[0068] Assume that the turning radius of the electronic warfare aircraft carrying the interference source is 8km, the beam width of the interference source is 0.7rad, and the natural communication distance of the target communication network is 40km. The simulation results are attached Figure 6 As shown, the interference effectiveness evaluation value of the circular route is 0.88, and the interference effectiveness evaluation value of the runway route is 0.99. It can be seen from the simulation result graph and the interference effectiveness evaluation value that the runway route is relatively better than the circular route.

[0069] simulation two

[0070] Assume that the turning radius of the electronic warfare aircraft carrying the interference source is 5km, the beam width of the interference source is 0.5rad, and the n...

Abstract

The invention belongs to the technical field of communication interference, and particularly relates to an onboard communication interference route modeling method and an interference efficiency evaluation method based on a radiation source. Aiming at a one-transmitting and multi-receiving ground communication net platform, two relatively good interference routes are designed, wherein an arbitrary point in the runway-type route can satisfy the domain suppressing conditions while the interference interruption duration in unit time is reduced as much as possible. Finally, the interference efficiency evaluation method is provided. The method includes the following steps that the parameters of the two routes are designed; sampling points are selected in the routes; the evaluation indexes of each point are calculated; the evaluation index values of the whole routes are obtained through the evaluation index value of each sampling point; the weighted sum is obtained after the evaluation indexes are normalized.

Description

technical field [0001] The invention belongs to the technical field of communication interference, and in particular relates to a radiation source-based airborne communication interference route modeling and interference efficiency evaluation method. Background technique [0002] Compared with general fixed station jamming equipment, airborne jamming equipment has the following advantages: it can fly close to the enemy's jammed radar, and the jamming distance is small; it can take advantage of its own movement and form some special jamming schemes to improve the target communication network station. Anti-jamming measures such as jamming effectiveness; therefore, the use of airborne jamming equipment for electronic jamming is a major trend in the development of future electronic countermeasure systems. [0003] For the ground communication network station of the one-send-multiple-receive system, usually only the location of the communication radiation source is known but the ...
