Radar Signal And Its Active Decoy Recognition Method And Implementation

With the wide application of various new radar technologies on the battlefield,the electromagnetic environment on the battlefield is more complicated and unpredictable.The enemy 's radar combat system is paralyzed in advance on the battlefield,which can effectively combat the enemy 's combat vision and communication capabilities,and quickly gain the opportunity and Initiative.Therefore,anti-radiation combat techniques against radar on the battlefield have become very important in modern battlefields.Aiming at the relatively common anti-radiation seeker passive radar,in order to protect its own radar combat system,the decoy technology that plays a role in defending the active radar signal against the enemy is also applied widely.In this paper,based on the relevant characteristics of the decoy signal,focusing on the identification and differentiation of the radar signal and the active decoy,the anti-bait technology involved in the anti-radiation seeker radar is researched as follows:(1)Several common radar characteristic parameter types are introduced,combined with the radar signals of different systems,the corresponding radar signal recognition method is given,and some simulation analysis of some of the common parameter estimation are given.Based on this,the similarities and differences of radar signal and decoy signal in these characteristic parameters are compared based on the paper title.(2)The influence of the bait system on the radar receiver is analyzed.The influence of the decoy signal on the deflection voltage at the receiver end and the measurement error caused by the deflection angle is explained,and the mechanism of decoy decoy on the seeker is explained.Based on the decoy mechanism,the decoy signal is given The characteristics of the working signal that should be provided for the identification and separation of the decoy later.(3)Based on the previous research,according to the possible interference scenarios of the decoy signal,from the perspective of energy and phase difference,the separation method when the decoy signal and the radar signal are highly coincident is analyzed,and the theoretical research and simulation are respectively carried out The point of view verifies the feasibility of the method and the boundary conditions of the method.Finally,a set of complete identification and distinguishing process of radar signal and active decoy is given.(4)This article combines the specific hardware platform and the actual debugging scenario,first introduces the hardware structure used,and then optimizes the software structure part of the entire hardware scene according to the actual conditions and test results of the system,and implements the hardware function was evaluated.
