Abstract :
We have theoretically demonstrated that the interference produced in a radar by multiple wideband mainbeam jammers can be cancelled using a set of appropriately located auxiliary antennas with adaptive tapped delay lines. Typical cancellation performance is illustrated, and design formulas are derived for the required number of auxiliaries and their gain, spacing, number of temporal taps, etc
