METHOD OF PROTECTING A RADAR AGAINST INTERFERENCE AND A RADAR FOR CARRYING IT OUT |
摘要 |
A process for protecting radars against jamming, in which a pseudo signal is transmitted simultaneously with the useful signal and is formed from pulses synchronous with those of the useful signal. The amplitude of the pseudo signal is higher than that of the useful signal in order that a countermeasure device hooks onto this pseudo signal and ignores the useful signal. The frequency of the pseudo signal differs sufficiently from that of the useful signal to ensure that the jamming signals, retransmitted by the countermeasure device on the pseudo frequency, are rejected in the intermediate frequency amplifier of the radar receiver. |
