Abstract :
Spectral analysis of the environment, often called sniffing, is used to find a clear operating band in radar and communication systems. The authors show that the sniffing technique can be used to null multiple broad-band sidelobe jammers by exploiting the transfer function of the antenna. Analysis and computer simulation are used to demonstrate the performance
