Abstract
A constant false alarm rate (CFAR) moving target indication (MTI) radar system, operable in various electronic countermeasures (ECM) environments is disclosed. A modified Dicke-Fix circuit is used to drive the MTI. Operation of the invention results in automatic restoration of signal level out of a filter. Thus the invention provides a CFAR-MTI that is not degraded significantly by swept jammers and is not captured by off-frequency jammers.
