摘要： An electronic device includes a transmission antenna that transmits a transmission wave, a reception antenna that receives a reflected wave, which is the reflected transmission wave, a controller that controls a radiation pattern of the transmission wave, a signal processor that detects an object on the basis of a transmission signal transmitted as the transmission wave and a reception signal received as the reflected wave. The controller performs control such that, when the transmission wave is transmitted a plurality of times in certain units, a transmission wave with a varied radiation pattern is included at least once. The signal processor outputs a result of the detection of the object on the basis of a selected cluster, whose area of a range over which a point group spreads is the smallest among a plurality of clusters obtained by performing clustering on results of detection performed on the object the plurality of times.

摘要： A radar device for automotive applications comprises a radar circuit configured to process a radar signal that has a first signal portion and a second signal portion, wherein the first signal portion occupies a first frequency band and the second signal portion occupies a second frequency band that is separate from the first frequency band. An antenna device of the radar device comprises a first and second antenna element that are both coupled to a common signal port of the radar circuit and the radar device is configured to route both the first signal portion and the second signal portion via the common signal port between the radar circuit and the antenna device. The antenna device is a frequency selective antenna device that transduces the first signal portion via the first antenna element and not via the second antenna element and that transduces the second signal portion at least via the second antenna element.

摘要： A power management circuitry for a radar level gauge including a first voltage converter, having a low-voltage end for receiving a drive voltage from a power interface and a high-voltage end for supplying an intermediate voltage higher than the required operating voltage, a temporary energy store arranged to be charged by the intermediate voltage, a second voltage converter, having a high-voltage end for receiving an input voltage from the energy store, and a low-voltage end for providing the operating voltage lower than the input voltage. By storing energy at a higher voltage, a different type of energy store (e.g. low capacity capacitor) may be used. As a consequence, the cost and start-up time of the energy store is significantly reduced.

摘要： FMCW-type radar level gauge (2) for determining the distance to the surface (7) of a product (6) in a tank (5) comprising a transceiver (11) to emit an electromagnetic transmit-signal and to receive an electromagnetic return-signal reflected by the surface (7), the electromagnetic transmit-signal having a bandwidth of at least 1 GHz, a relative bandwidth (max frequency / min frequency) of less than 2.5 and an upper frequency-limit smaller than 4 GHz. The gauge (2) comprises a single conductor probe (9) mechanically suspended and extending into the product (6) in the tank (5), and a matching arrangement providing an electrically-matched connection between a sealed electrical feed-through (21) and the single conductor probe (9). The relatively expensive still-pipe of the prior-art is here replaced with a relatively inexpensive single conductor probe (9) acting as a surface wave-guide (SWG).

The configurable lCs may be similar or identical, and have an allocated measurement range. Each configurable IC comprises: a down-converter; an ADC; a digital signal processor; and a transmitter to transmit a radar signal. One is configured as a master IC and to transmit a radar signal and each of the other configurable lCs to operate as a slave IC. Each configurable IC is adapted to use a common Local Oscillator signal, a common clock signal, and a common timing signal for determining at least the start of the common sampling window. A method of operating such a multichip radar system is also disclosed, as is a configurable IC or radar IC suitable for such a system.
