SIMULTANEOUS SIGNALS IN IFM RECEIVERS

The problem of frequency measurement by an IFM receiver when there are two or more simultaneous signals is considered. The problem is differ ent from other frequency estimation problems considered in the literat ure since the IFM receiver is an extremely wideband device and reliabl e estimation is required for short pulse signals, A fast algorithm for estimating the frequencies of all the simultaneous signals is propose d. Computer simulations of the technique are compared with performance analyses.
