Research On Active Technology Of Missile Penetration

In Information warfare environment,Ballistic missiles because of its high precision,fast,surviving ability,the attact effect is obvious with a series of advantages,widely used in various countries to the battlefield,to achieve a better deterrent effect.In view of the important role of radar in the military field,the study of ballistic missile jamming technology has become an important research direction in the field of radar confrontation.In this paper,the body of this paper is to study the active jamming technology of missile penetration,and to study the coherent blanket jamming,ISAR image blanket jamming and rotational precession jamming.The main contents of this paper are composed of three parts:In the first part,we study the coherent blanket jamming technique for LFM radar signal.The basic principle is analyzed and analyzed,and the simulation results of the jamming effect are presented.Combined with the actual hardware circuit,A novel project of blanket joint jammer is presented;In the second part,we study the jamming of interrupted-sampling pseudo-code modulation for two-dimensional ISAR imaging jamming.The ISAR image radar is generated by intermittently sample for the intercepted radar signals and then performing pseudocode phase modulation,compared with the traditional noise interference,this jamming method makes the spectrum broadened,effectively hide the real target.In the third part,the electromagnetic scattering characteristics of the typical ballistic missile warhead are simulated with the background of ballistic missile penetration,and the electromagnetic scattering characteristics of the radar echo are analyzed.From the motion characteristics of the rotational precession target,A Novel Method for Generating ISAR jamming signals.according to the precession target model,the position of the jammer and the false target is calculated in real time,and the false target with real motion trajectory is generated,so as to realize the effective confrontation of the true and false target radar based on the trajectory plane.
