摘要： PROBLEM TO BE SOLVED: To simplify the constitution of an azimuth measuring apparatus which irradiates a target with an electromagnetic wave and receives the electromagnetic wave reflected by the target to measure the direction of the target.SOLUTION: An oscillator 10 generates a signal which is a pulse wave, and a transmission antenna 11 is a leakage wave antenna. The leakage wave antenna changes in beam direction with frequencies. The pulse wave has a spread in frequency, so the signal differ in radiation direction with frequencies. Consequently, the signal reflected by the target and received by the reception antenna 12 has a frequency spectrum different with the azimuth of the target. The received signal is transmitted through BPFs 14A-14C and the signal intensity is measured to detect in which of three directions the target is.
