ABSTRACT:
A jamming analysis and transmission selection system for a radar wherein the frequencies present in the environment are sampled during a discrete time interval following each radar transmission; and utilizes a surface acoustic wave device having a plurality of spaced groups of interdigitated fingers on a substrate wherein each of said groups has a finger width and spacing to be resonant at each of a plurality of anticipated different interfering frequencies. The output of the device is sampled following each discrete time interval to identify the presence of the selected interfering frequencies to change the transmission frequency of the radar transmitter to a non-interfering frequency.
