  • In stepped frequency radar, the velocity of targets must be estimated and compensated to eliminate the range migration and distortion due to target moving. The conjugation method is presented for velocity measurement in stepped frequency radar. And a prototype of a stepped frequency system with dual carrier frequencies is proposed. With processing approach proposed, the system has both the advantage of high range resolution of stepped frequency radar and the capability of high precise velocity measurement. The estimated velocity can be used to compensate range migration and distortion in radar imaging. Therefore, the dual-carrier-frequency stepped-frequency radar can achieve high precise velocity measurement and high resolution simultaneously.
