Abstract
An improved countermeasure technique for providing jamming signals againstobing radar, especially COSRO (conical scan on receive only) radar. A power spectrum (or comb) is generated having specific spectral line separation over a frequency band of the expected range of scan frequencues. The line spectrum, preferably having a flat topped envelope is then swept as a unit so that all frequencies with in a range of expected scan frequencies are traversed at least once by a spectral line. The swept comb is used to modulate a repeater pulse train transmitting to a lobing radar. The sweep of the comb causes at least one spectral line to beat with the scan frequency of the radar resulting in antenna oscillation and sidelobe lockup by deception of the angle-tracking circuits of the radar.
