By producing false signals by self-deceptive jammers and sending them to the enemy's radars, it is possible to deceive the radar and hide the self-targets that are within the radar's range of vision. For this purpose, the deceptive jammer receives the enemy's radar signal and after applying the appropriate frequency shift and time shift on it, it deceives the radar by the DRFM system located on the jammer

and sending a set of these fake signals to the enemy's radar. . Now, the basic issue in this method is, what should be the appropriate time shift and frequency shift interval to create deception signals? If the frequency and time shift distance is small, it means that the number of decoy signals should be increased, which has the advantage that it is easy to hide the internal target from the enemy's radar, but the problem will be that the PAPR value of the system will increase. The search and efficiency of the jammer decreases, and if the frequency and time shift distance increases, because the number of fake signals decreases, so there is an advantage that the PAPR value will not increase, but there will be a problem that the internal target will not be easily hidden from the enemy's radar. stayed Therefore, the frequency and time shift distance should be calculated in such a way that both the PAPR criterion does not increase and the target is easily hidden from the enemy's radar.
