摘要

Dual-frequency radar is a preferred solution for moving target localization because of its low complexity and cost. Although several studies for dual-frequency radar are addressed in the literature, all of those methods are designed for the synchronous mode. In this letter, a new localization method based on phase compensation is proposed for dual-frequency radar in the asynchronous mode. Compared with the synchronous mode, the proposed method is suitable for most commercial short-range radars with the single local oscillator architecture and can provide a cost-effective solution. Moreover, both the theoretical variance and Cramer-Rao lower bound are derived for the performance analysis in the asynchronous mode. Computer simulations were conducted to verify the validity of the proposed method.
