摘要: A multicopter includes: motors to respectively rotate three or more rotors; and a radar system to transmit and receive a signal wave and detect a target by using the signal wave. An object detection apparatus in the radar system transmits and receives a signal wave to perform a target detecting process. An antenna element is in a position to receive the transmission wave reflected off a rotor (a rotor-originated reflected wave). The signal wave received at the antenna element is inclusive of a target-originated reflected wave reflected off a target and a rotor-originated reflected wave. The apparatus determines whether or not a frequency band satisfying a predefined condition for identifying a frequency peak is contained in a frequency spectrum of the signal wave as received by the antenna element, and determines a peak of a frequency band satisfying the predefined condition to be a frequency of the target-originated reflected wave.

摘要: A coaxial guided wave radar apparatus includes a central conductor configured as a wire rope. One or more spacers can be positioned and held in place about the central conductor at predetermined lengths along the central conductor, wherein each spacer is positioned and held in place along the central conductor by one or more respective retainers that are crimped to the central conductor. A tensioner can be attached to the end of the wire rope of the central conductor. The tensioner allows for a proper tension to be applied to maintain a spacing of the wire rope from an outer conductor.

摘要: Bracket structures that structurally support and enhance the performance of millimeter-wave tapered-slot end-fire antennas for use in vehicular radar systems. The system includes a first longitudinal rib and a second longitudinal rib, each defining a first longitudinal slot and having a transmission end and a chip connection end. The system includes a crossbeam coupled to the first longitudinal rib and the second longitudinal rib. The system includes a first end-fire antenna having a transmission end that is received by the first longitudinal slot and a chip connection end. The first end-fire antenna is designed to transmit a first signal having a first phase. The system includes a second end-fire antenna having a transmission end that is received by the second longitudinal slot and a chip connection end. The second end-fire antenna is designed to transmit a second signal having a second phase that is different than the first phase.

摘要: A tank arrangement including a guided wave radar level gauge installed in a tank, and having a single wire transmission line probe extending through a passage through a conducting structure in the tank. Along the section of the probe that extends through the passage, the arrangement comprises a propagation field limiting structure adapted to reduce a propagation field of an electromagnetic signal propagating along the probe. With this design, the radial extension of the propagating field can be locally reduced so that a sufficient portion of the signal power is allowed to pass through the passage.

摘要: The present disclosure relates to a radar apparatus and an antenna system for the radar apparatus. A first transmitting antenna group and a first receiving antenna group are constituted by elongating some of a plurality of transmitting antennas and a plurality of receiving antennas in a first direction of vertical directions, a second transmitting antenna group and a second receiving antenna group are constituted by elongating the other antennas in a second direction opposite to the first direction, transmitting antennas to transmit transmission signals and receiving antennas to receive reflection signals reflected from an object are appropriately selected, thereby being able to improve horizontal and vertical angular resolving power in both of mid/long-range sensing and short-range sensing.

摘要: An antenna device is disclosed, including a control means and at least two transmission means in predeterminable positions and at least two receiving means in predeterminable positions. The control means is set up in such a way that it alternately individually excites the at least two transmission means in transmission, in such a way that each of the at least two receiving means receives a transmitted signal generated by each of the at least two transmission means. The control means is further set up to excite the at least two transmission means jointly in transmission at a predeterminable moment in such a way that each of the at least two receiving means receives a transmission signal generated by a single virtual transmission means.
