ABSTRACT:
A microwave frequency detection receiver utilizing a prescaler comprised of one or a plurality of cascaded analog frequency dividers for down-converting received microwave signals to a predetermined compressed radio frequency bandwidth, connected to a combined frequency discriminator and quantizer processor. The frequency discriminator can be either a single or multiple delay line discriminator or a two-stage feed forward digital instantaneous frequency measurement device. The receiver is characterized by wide radio frequency input bandwidth as well as accurate frequency measurement capability on short single pulse signals. Delay line discriminators can operate with high data rates and in a dense signal environment with a high probability of accurate signal frequency detection and measurement, and are thus suitable for use in electronic warfare systems.
