    摘要： A transmit system for collision avoidance systems having autocalibration. A four element antenna array (10) is provided. Each element (12, 14, 16, 18) is selectively connectable to a transmitter (20) through a power divider (22) and an isolator (24, 26, 28, 30). Three of the elements (14, 16, 18) further have a programmable phase shifter (34, 38, 42) in line to the transmitter (20). A phase detector (46) having a first input selectably connectable to one of the elements and a second output connected to the transmitter is provided. By selectively connecting one element to the transmitter (20) and one element to the phase detector (46) and then selectively programming the appropriate phase shifters (34, 38, 42), the differentiated phase delay in each channel of components associated with an antenna element can be calibrated.

    摘要： A supervision method for a flight state of an unmanned aerial vehicle, comprising: generating, according to off-line flight application information, an off-line flight certificate for the unmanned aerial vehicle, and providing the off-line flight certificate to the unmanned aerial vehicle, thereby restricting flight behaviour of the unmanned aerial vehicle in an off-line flight mode according to the off-line flight certificate; or, reporting flight information about the unmanned aerial vehicle, determining, according to pre-set safe flight parameters, whether the flight information about the unmanned aerial vehicle conforms to a flight safety regulation, and generating, when determining that the flight information about the unmanned aerial vehicle violates the flight safety regulation, a corresponding flight restriction instruction, and sending the flight restriction instruction to the unmanned aerial vehicle for execution, thereby restricting flight behaviour of the unmanned aerial vehicle in an on-line flight mode. The present invention further relates to an unmanned aerial vehicle, a supervision system for a flight state of an unmanned aerial vehicle, a monitoring system, a processor and a memory.

    摘要： There is provided a method for determining a position of a user device in relation to a vehicle, the vehicle comprising a first and a second receiver. The method comprises transmitting a positioning signal by the transmitter comprised in the user device, receiving the positioning signal by the first receiver and by the second receiver being arranged at a distance from the first receiver; in at least one of the first and second receiver, receiving and identifying a reflected positioning signal having been reflected at a ground surface before reaching the receiver; performing time synchronization between the transmitter and the first and second receiver; determining a position of the user device in a three-dimensional coordinate system based on the time-of-flight of the positioning signal received in the first and second receiver and on the time-of-flight of at least one reflected positioning signal received by at least one of the first and second receiver.
