In the case of only the bloom, a bloom center-of-gravity position signal is output, or in the case of both the body and the bloom, a body center-of-gravity position signal is output together with a determination result signal. A relative distance is calculated from a relative speed signal and an initial relative distance signal to be output from a signal processor 4, and a relative distance signal is output. If a determination result signal to be output from a bloom/body determination discriminator 8 is only the bloom, the sum of the value obtained by adding an error signal to a bias amount in response to the relative distance signal and a steering command signal is used as a steering compensation signal. If the result signal is both the body and the bloom, a steering command signal to be output from an auto-pilot 6 is output as a steering compensation signal.
