Abstract

The invention discloses a method for simulation design of range gate pull-off active jamming. The method comprises the following steps of: S1, establishing a range gate pull-off jamming simulation model; S2, carrying out parameter transfer between the range gate pull-off jamming simulation model and an anti-ship missile terminal guidance radar simulation model; and S3, in a pull-off period, obtaining a reception pulse of an anti-ship missile terminal guidance radar in real time, in an initial stage, setting a forwarding delay time as a minimum forwarding delay and forwarding an jamming pulse according to the forwarding delay time; entering a pull-off stage, calculating forwarding delay time during linear pull-off and parabolic pull-off through the range gate pull-off jamming simulation model and forwarding the jamming pulse according to the forwarding delay time; entering a pull-off retention stage, assigning a fixed value for the forwarding delay time and forwarding the jamming pulseaccording to the forwarding delay time; and entering a stopping stage and stopping forwarding the jamming pulse. The method can be used for improving the design of jamming modes and jamming parametersof range gate pull-off active jamming, and improving the jamming effect.

Description

technical field [0001] The invention relates to the field of simulation test verification, in particular to a simulation design method for range gate towing active interference. Background technique [0002] The shipborne active jamming system suppresses or deceives enemy electronic equipment through artificial radiation and forwarding of specific types of electromagnetic waves, and plays an important role in air self-defense operations. Range gate towing is the main deception method for the automatic range tracking system of anti-ship missile terminal guidance radar. [0003] The traditional range gate towing active jamming simulation method establishes an evaluation model for key parameters of range gate towing, and inputs fixed jammed radar parameters during simulation, which is mainly used for uniform velocity gate towing and uniform acceleration wave Door towing is simulated and evaluated. The simulation process does not involve the real-time parameter transfer betwee...
