Electronic Deception Jamming: False Target Generation in Radars

This paper presents the technique of false target generation in radars, also known as electronic deception jamming techniques. Many countermeasure techniques have been developed over the time, which not only degrade the effectiveness of the radar but also, are able to completely deny the target information to the radar. False target generation is one of the deception jamming techniques, which refers to sending the false information of the target intentionally by creating single or multiple false echoes of the target along with the real target echo. For that purpose, a radar signal is intercepted and radar signal parameters are extracted after the complete analysis of the received signal which are then used to create false targets of same specification as that of the radar echo signal. The jammer can be made more realistic if these false targets are sent before and after the real target echo. This paper focuses on the single and dense false targets generation for the Linear Frequency Modulated (LFM) waveform based pulsed Doppler radar. Its effectiveness is verified through several simulations for different ranges.
