Filed: 1982-03-08
Abstract: PURPOSE:To remove unnecessary waves for a short time by shifting plural antenna beams and discriminating a beam by receiving arrived radio waves by the frequency of shifts up to the reduction of the level of a received signal. CONSTITUTION:Plural antenna beams B1, B2- are formed so that a directional zero point is composed in the arriving direction theta3 of a required wave by controlling a phase shifter connected to plural element antennas and only an unnecessary wave is received. The whole beams are shifted in the beam direcrtion by each interval between adjacent beams until the receiving level is reduced; if the receiving level is reduced by the 3rd shifting, the reception of the unnecessary wave is detected by the beam B3. Subsequently, a difference beam consisting of a monopulse is formed in the arriving direction of the unnecessary wave and the main beam is oriented in the arriving direction of a required wave to obtain a radiation pattern forming a zero point in the arriving direction of the unnecessary wave.

Abstract: PURPOSE:To prevent an erroneous detection by constituting a device so that a set condition of a transmission pulse for an original detection is changed by detecting the influence by a reflected wave whose time interval is longer than that of a reflected wave of a detection object body. CONSTITUTION:In order to judge whether a multiple reflected wave exists or not, for instance, in the case of a safety device of an elevator door, a single pulse 2a is transmitted experimentally in the course of opening a door for which a function of the safety device is unnecessary. For instance, after transmitting a single transmission wave 2b transmitted by the single pulse 2a for transmitting the single pulse 2a experimentally in the course of opening a door for which a function of the safety device is unnecessary in the case of the safety device of the elevator door, reception of its transmission wave is confirmed by a multiple reflected wave confirming circuit 10. When a receiving wave exists, an erroneous detection is judged from an overlap of a multiple reflected wave output 2e and a waveform 2f of a gate circuit 5.
