ABSTRACT:
A radar jamming system comprises a target vehicle and a slave vehicle. A master thread radar detection system is provided in the target vehicle and a slave transmitter system in the slave vehicle with a data link between the target vehicle and the slave vehicle. A threat analyzer is carried by the target vehicle, the threat analyzer being capable of measuring the distances between the target and thread radar as well as between the target and slave vehicle and includes means for calculating a suitable time delay signal and doppler shift for masking the target. The signals are transmitted to said slave vehicle by the data link and means carried by the slave vehicle under control of the data link generate and transmit a radar pulse having the calculated time delay and doppler shift. The signal emitted from the jammer is coincident with the signal reflected from the target in both time and frequency.
