Abstract

The invention discloses a simulation design method for range gate towing active interference, comprising: S1, establishing a range gate towing interference simulation model; S2, using the range gate towing interference model and anti-ship missile terminal guidance radar Parameter transfer between simulation models; S3. In a towing cycle, obtain the receiving pulse of the anti-ship missile terminal guidance radar in real time. In the initial stage, set the forwarding delay time to the minimum forwarding delay, and forward the interference pulse according to the forwarding delay time ;Enter the towing stage, calculate the forwarding delay time during linear towing and parabolic towing through the distance gate towing interference simulation model, and forward the interference pulse according to the forwarding delay time; enter the towing maintenance stage, take a fixed value for the forwarding delay time, The interference pulse is forwarded according to the forwarding delay time; enter the stop phase, and stop forwarding the interference pulse. The invention can be used to improve the design of the interference mode and interference parameters of the range gate towing active interference, and improve the interference 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...
