<p>PURPOSE:To obtain a stable azimuth signal wherein the change portion in a bow direction was subtracted from a scanner azimuth signal, by providing a bow direction change speed detection sensor and correcting the azimuth signal generated from a scanner azimuth signal generator by the output signal of said sensor. CONSTITUTION:The video signal obtained from a radar transmitter-receiver 11 is amplified by a video amplifier 12 to be supplied to a video memory 15 while a counter 27 generates a scanner azimuth signal showing the hourly azimuth of a scanner based on a bow azimuth. When the bow azimuth changes, the signal corresponding to the angular speed at that time is generated from a rate gyrocompass 21 and integrated by an integrator 22 to calculate the angle of the bow shifted from a route. Because the signal showing this angle is supplied to an adder 29, the shift amount of the bow is subtracted from the scanner azimuth signal by yawing.</p> |
