Abstract
Due to the long dwell time required for doppler processing, most doppler systems are particularly vulnerable to electronic counter measures environments (jamming). Such vulnerability manifests itself by registering numerous false alarms and by receiver saturation. The proposed system will not deviate significantly from an ideal constant false alarm rate (CFAR) device when operated in an electronic countermeasure (ECM) environment nor will its sensitivity degrade as in conventional systems.
