摘要： Radar detection of an object is achieved by identifying a first range associated with a possible object based on a first return from a first radar transmission having a first chirp rate, and identifying a second range associated with the possible object based on a second return from a second radar transmission having a second chirp rate that differs from the first chirp rate. The first and second ranges are evaluated together to determine whether the possible object is a true object.

摘要： A guided wave radar level measurement device includes a process connection composed of an outer conductor and a central conductor. The central conductor is surrounded at least in part by a dielectric material. One or more resilient metal seals can be employed to form a hermetic seal around a portion of the probe. The metal seal protects the dielectric material such that the hermetic seal is isolated from process and temperature shock. The metal seal(s) can be further mated with one or more insulators and one or more gaskets, the metal seal(s) to provide a thermal and mechanical barrier as well as offering chemical resistance to the guided wave radar level measurement apparatus.

摘要： A pulse compression radar for performing pre-distortion is provided, which has a configuration simplified in circuit structure. A radar apparatus (pulse compression radar) includes an antenna configured to externally transmit a transmission signal transmitted by a power amplifier and receive a reflection signal caused thereby as a reception signal. The radar apparatus includes a reception circuit configured to propagate this reception signal to a radar image creating module. The radar apparatus corrects beforehand, by utilizing the transmission signal (feedback signal) transmitted from the power amplifier, a transmission signal to be inputted into the power amplifier so as to cancel distortion of the transmission signal caused by amplification effect of the power amplifier. Further, a circuit where the reception signal passes and a circuit where the feedback signal passes share a part of each other.

摘要： An apparatus for determining the fill level of a fill substance in a container, comprising at least one antenna element. The at least one antenna element has a hollow conductor, wherein there is arranged at a first end region of the hollow conductor a coupling element for the out-coupling of transmission signals and for the in-coupling of received signals, wherein there is arranged at a second end region of the hollow conductor a radiating element directed toward the fill substance, a transmitting/receiving unit having a signal generator for producing the transmission signals. The transmitting/receiving unit determines the fill level of the fill substance in the container based on the travel time of the transmission- and received signals. The connecting line and/or the hollow conductor are/is embodied in such a way that the transmission signals are transmitted time delayed, so that the distance between the at least one antenna element and the surface of the fill substance is virtually increased and the received signal is isolated in time from disturbances of the transmitting/receiving unit, which arise in the case of producing the transmission signals.

摘要： A radar apparatus using a pulse pair method to quickly measure a relative speed of an object. The radar apparatus includes: A data acquirer that acquires data relating to a pulse width, a repetition frequency, and a highest staggered ratio; A staggered pattern output unit that outputs a specific staggered pattern in which a total of phase changes within a sweep range of the target of the pulse pairing can be approximated to zero, wherein each phase change is caused by the pulse pairing on a target object at a constant speed due to a difference between an average transmission interval and a transmission interval between transmissions within the sweep range; And a setter that sets the transmission interval of a pulse signal by using the pulse width, the repetition frequency, the highest staggered ratio, and the specific staggered pattern.

摘要： Under control of a first transmission code controlling section, a first radar transmitting section periodically transmits a first radar transmission signal with a first transmission period based on a first transmission trigger signal produced after elapse of a first delay time period from reception of a predetermined synchronization establishment signal by a first transmission trigger signal producing section. Under control of a second transmission code controlling section, a second radar transmitting section periodically transmits a second radar transmission signal with a second transmission period similarly. In accordance with the first delay time period and the second delay time period, arrival times of interference signals from the first radar transmitting section and the second radar transmitting section are within transmission zones of the second radar transmission signal and the first radar transmission signal.

摘要： A target object detection apparatus is provided. The apparatus includes a transmitter, a receiver, a threshold determiner, a parameter setter, a parameter selector, and a timing controller. The transmitter repeatedly transmits a transmission pulse at a transmission timing. The receiver receives a reception signal at a reception timing set based on the transmission timing. The threshold determiner determines whether an amplitude value of the reception signal exceeds a predetermined threshold at every sampling point and counts the number of sampling points at which the amplitude value of the reception signal exceeds the threshold. The parameter setter sets a plurality of different parameters for controlling the transmission timing. The parameter selector selects the parameter from the parameter settings, to minimize the number of sampling points counted by the threshold determiner. The timing controller controls the transmission timing, based on the parameter selected by the parameter selector.
