摘要： In a radar device, a wide band filter unit suppresses unnecessary components contained in a reception signal subjected to frequency conversion by a frequency conversion unit. The wide band filter unit has frequency characteristics for performing filtering so that isolation between transmitting and receiving becomes a desired level or lower. Although the wide band filter unit has an increased noise power compared to a matched filter, the wide band filter performs the filtering so as not to round a pulse waveform.

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 radar apparatus for a ship comprises a solid state transmitter and/or receiver enclosed within a housing, and an antenna coupled to the solid state transmitter and/or receiver. The external shape of the housing is substantially frusto-pyramidal. The frusto-pyramidal shape of the housing contributes to the robustness of the radar apparatus and allows the apparatus to have a low radar cross section.

摘要： The present invention relates to a pulsed level gauge system comprising frequency control circuitry. If an acquired signal indicates that the time between the previous filling level determination and the present filling level determination is shorter than a predefined time, the frequency control circuitry controls at least one of a transmit signal generating circuitry and a reference signal generating circuitry comprised in the pulsed level gauge system using previous frequency control settings stored in memory. If the acquired signal indicates that the time between the previous filling level determination and the present filling level determination is longer than the predefined time, the frequency control circuitry iteratively regulates at least one of the transmit signal generating circuitry and the reference signal generating circuitry towards achieving a desired pulse repetition frequency difference between the pulse repetition frequency of the transmit signal and the pulse repetition frequency of the reference signal.

摘要： According to one aspect of the inventive concept there is provided a transmitter-receiver system comprising: a transmitter arranged to transmit a wavelet; a receiver arranged to receive a wavelet; a wavelet generator arranged to generate a reference wavelet; and timing circuitry arranged to receive a reference clock signal, output a first trigger signal for triggering transmission of a wavelet and output a second trigger signal for triggering generation of a reference wavelet. The timing circuitry further comprises a delay line including at least one delay element and being arranged to receive a signal at an input of the delay line and transmit a delayed signal at an output of the delay line, wherein a state of each delay element of at least a subset of said at least one delay elements is switchable between at least a first state and a second state. A delay element in said first state, i.e. switched to its first state, presents a first propagation delay. A delay element in said second state, i.e. switched to its second state, presents a second propagation delay which differs from the first propagation delay by a value which is smaller than a period of the reference clock signal. Thereby a total propagation delay of the delay line is configurable by controlling the state of each delay element of said subset. The system further comprises a controller arranged to control a delay between the first trigger signal and the second trigger signal by controlling the total propagation delay of the delay line. The system is arranged to correlate the reference wavelet with a received wavelet for at least one setting of the total propagation delay.

摘要： In a wind profiler, the number of acquisition ranges is expanded up to heights where noise is introduced into a received signal, even in the case where noise due to transmit/receive switching is introduced. Provided is a signal processing device (103) in a wind profiler that emits an electromagnetic wave pulse into a space, switches from transmitting to receiving, receives an electromagnetic wave reflected from a target to be observed, and measures wind speed from a Doppler frequency of the received electromagnetic wave, and is equipped with a unnecessary data determiner (10) that detects a noise section in which switching noise occurs due to the switching between transmitting and receiving, and an unnecessary data eraser (3) that converts a received signal in the noise section to substantially insignificant data.

摘要： An apparatus for determining the position of a target object using a two-channel monopulse radar. The radar may include two transmitting antennas and one common receiving antenna disposed in a coplanar arrangement. The transmitting antennas may be positioned on the focal plane of the radar along a focal plane axis that extends through, and that is perpendicular with, a boresight axis of the radar. The transmitting antennas may be spaced apart from one another in a first dimension a distance equal to about one half of one wavelength of the radar's center operating frequency. One of the transmitting antennas may be squinted at an angle of θ
1 relative to the boresight axis and the other transmitting antenna may be squinted at an angle of θ
2 relative to the boresight axis in a second dimension. The transmitting antennas are not squinted relative to one another in the first dimension.
