Multipath Blanking in Shipboard IFM Recievers

Suppression of multipath reports by a system receiver, which allows the host system processor to process the real environment and retains the intercept capability of the instantaneous frequency measurement (IFM) receiver
Multipath Blanking in Shipboard IFM Receivers William B. Sullivan Wide Band Systems Inc. Rockaway, NJ Shipboard electronic support measure/RF collection systems are particularly susceptible to errors due to multipath effects where the receiver observes not only the direct path signal from the emitter, but also signals reflected from the...
