Abstract

Phase noise compensation can be performed in a primary radar system, such as in transceiver hardware. A first reflected reception signal can be received, corresponding to a reflection of a first transmission signal from an object, and a first measurement signal can be generated using mixing or correlation of the first reflected reception signal and the first transmission signal. A second measurement signal can be similarly generated from a second transmission signal and a second reflected reception signal. The first and second measurement signals include respective components including complex conjugate representations of each other. The components correspond to interfering components associated with phase noise, and such respective components can cancel each other to suppress phase noise.
