Experimental Wideband Multi-Channel Cancellation Performance

Abstract

For future radars with a wideband capability, effective electronic protection algorithms are required to perform target detection and discrimination. The Radar Division of Naval Research Laboratory has developed a flexible, adaptive wideband (400 MHz) multi-channel digital receiver/canceller test bed to investigate a radar's capability to reject interference. The effects of varied inter-channel hardware mismatches and intra-channel analog-to-digital aliasing on wideband cancellation performance are investigated. It is found that 23 dB of self-cancellation can be achieved with a proper combination of receiver implementation and cancellation configuration.
