One thing to note is that 4G car radar jammers usually have a range advantage over target radars. Indeed, the signal from the radar indicates that when the target bounces, the trajectory loss is 1/R2 and the radar return is 1/R4. With these points in mind, let us consider the different types of radar jamming methods defined in electronic warfare. The barrage attempts to submerge the jamming signal in the receiving band of the radar receiver. Noise uses phase or AM noise to modulate spurious signals. Spoofers use repeaters or memory to generate copies of radar echoes and make appropriate changes in time or frequency. Repeated interference will modify and retransmit the received radar signal, so the generated echo will relay the inaccurate position. Similarly, a transponder is a type of transponder that can copy the stored signal copy after receiving a radar signal trigger signal.
