Abstract: PURPOSE:To obtain a locator which makes possible the locating of a correct position of a sonobuoy quickly and stably with a simple construction by measuring a distance between the sonobuoy and an aircraft based on time information overlapped on a sonobuoy signal. CONSTITUTION:When an aircraft receives a sonobuoy signal 300 transmitted from a sonobuoy 300 at one point, the signal is expanded oppositely by a code the same as a spectrum expansion code used in expansion with a spectrum expander 4 to be demodulated to the original sonobuoy signal. A comparison is made between time information of the sonobuoy overlapped on a demodulation signal and the time of the reception of the signal to detect the time until the sonobuoy signal reaches the aircraft after the transmission of the sonobuoy signal from the sonobuoy 300 and the time detected is multiplied by light velocity to obtain a distance. Likewise, the distance is obtained at other points to locate the position of the sonobuoy 300 by the theory of trigonometrical survey. This makes possible accurate location regardless of flying attitude or the like while facilitating the locating of a number of sono buoys simultaneously.
