Abstract: PURPOSE:To suppress the reduction of amplitude of a reproduction signal by detecting each peak value of pilot signals reproduced from video tracks adjacent to a main video track and controlling the rotary heads at an equal maximum scan width on said both adjacent video tracks. CONSTITUTION:A gate circuit 35 of a tracking error detecting circuit 26 is closed, and a differential amplifier 33 delivers a tracking signal Tr. A rotary head reproduces and scans a video track B2 to which a pilot signal is recorded. Under such conditions, the pilot signals reproduced from tracks A2 and A1 which are adjacent to the track B2 are supplied to the circuit 26 as signals P. The peak values of detected signals fH and 3fH are held by peak holding circuits 38 and 39 while the head reproduces and scans the next track A1. Meanwhile a gate circuit 34 is closed, and the values held by both circuits 38 and 39 are delivered via the amplifier 33. Thus an equal maximum scan width is secured for the head between both adjacent tracks. This can suppress the reduction of amplitude of a reproduction signal.

Abstract: PURPOSE:To make a pseudo target signal come nearer to a signal reflected from a real target by setting the pulse width and the pulse repeating time of the pseudo target signal with the aid of compressing them by the amount of effect by the speed of its own machine. CONSTITUTION:When the speed of its own machine which transmits a radio wave is not negligible with respect to the propagation velocity of the radio wave, a relative speed arithmetic operation part 1 obtains a compression rate K and controls the oscillation frequency of a variable frequency reference signal generation part 2 to be K-fold. Moreover, a speed counter part 4 receives a speed information signal (a) and generates a smoothing clock signal 7 every time corresponding to distance resolution with respect to the speed. Besides, a range delay part 4 receives a distance information signal (b) and generates a delay time signal 8 corresponding to a distance. A signal 7 and the signal (b) are inputted to a pulse delay part 6 and the pseudo target signal whose pulse width and repeating time are made to be 1/K-fold is generated. Thus, the pseudo target signal is made to come nearer to the signal reflected from the real tartget.
