Abstract

Abstract : False alarms and misdetections caused by the carrier leakage problem attract increasing attention for resource‐limited platforms. To tackle the problem, we propose a target protected carrier leakage cancellation algorithm to rebuild the leakage signal from reference cells with those cells randomly updated based on each detection result to exclude the targets. The proposed algorithm eliminates the carrier leakage effectively without introducing false target due to the non‐involvement of the target information in the reference cells based on a random update strategy. The noise level of our proposed algorithm is less than that of the commonly used algorithms such as the Cell average constant false alarm rate (CA‐CFAR) detection method. As verified in the simulations, the proposed algorithm performs better than the CA‐CFAR method.
