PROBLEM TO BE SOLVED: To provide a guidance device for detecting a target machine at close range to enable warhead detonation. SOLUTION: This guidance device loaded on an airframe and tracking on a target to guide the airframe to the target, includes an antenna unit 8 transmitting radio waves toward the target and receiving the reflected waves from the target, an antenna controller 20 selectively forming the beam of radio waves of a first angle or a second angle wider than the first angle, an exciting receiver 9 selectively performing first transmission for transmitting the radio waves at a first transmission interval and second transmission for transmitting the radio waves at a second transmission interval shorter than the first transmission interval, a distance detector 13 for detecting a relative distance to the target on the basis of the received reflected waves, and a switching controller 15 for transmitting the radio waves with the beam of the first angle and the first transmission interval in an initial state, and switching the radio waves to the beam of the second angle and the second transmission interval at a time when the relative distance becomes shorter than a prescribed distance.
