Review of development of radar waveform countermeasure technology
With the advancement of sensor technologies,such as radar and electronic reconnaissance,the manipulation of the electromagnetic space has evolved from that of energy and frequency toward higher-dimensional waveforms,leading to the emergence of radar waveform countermeasures.The background against which the radar waveform countermeasure technology emerges and its conceptual connotation is presented.After introducing the current status of the technology,the establishment of the radar waveform"Observation,Orientation,Decision,Action"(OODA)loop is proposed using the game theory.The winning mechanism is achieved by camouflaging,jamming,and using radar waveforms to create battlefield fog and new kill chain effects.Furthermore,several key technologies and their principles in revealing radar waveform countermeasures,such as waveform concealment,waveform reconstruction and utilization waveform agility based counter-reconnaissance,are briefly described.Finally,the development recommendations for winning electromagnetic space through radar waveform countermeasures are proposed from three aspects.
