Now there is a term I havent heard before...spread spectrum like GPS, yes...but spread spectrum radar...hmmm... Did you misspeak or are we flying such radar now?

All modern AESA radars are considered "Low Probability of Intercept" (LPI) radar.

One of their characteristics to help in avoiding detection is using an ultra-wideband TX-RX and frequency hopping within that wide band, changing frequency every pulse.

In essence a form of Spread Spectrum radar.

Ok, frequency hopping I am familiar with. Thanks.
