Abstract: A radar sensor for use within a vehicle includes blockage detection functionality. In at least one embodiment, the radar sensor collects information on stationary infrastructure around the vehicle. The infrastructure information may be used to generate a Doppler Monopulse Image (DMI) or other graph for the sensor. A clutter ridge within the DMI or other graph may be analyzed determine a blockage condition of the sensor (i.e., unblocked, partially blocked, or fully blocked).

Abstract: A radar device includes a transmission part that transmits a radar wave which has been frequency-modulated such that one measurement cycle has a rising section in which a frequency increases and a falling section in which a frequency decreases, a reception part that derives respective beat signals of the rising section and the falling section, and a signal processor that performs a precipitation determining process on the basis of an analysis of the beat signals. In the precipitation determining process, in the absence of objects other than precipitation objects from a transmission range of the radar wave, it is determined whether a spectral similarity of the frequency spectra of the rising and falling section with precipitation reference spectra is not less than a threshold, and if the spectral similarity is not less than the threshold as a result of the determination, it is determined that precipitation is present.

Abstract: A system is provided that includes a Doppler radar unit that transmits a first electromagnetic wave having a first frequency, which a test system converts to a first electrical signal having the first frequency. The test system generates a second electrical signal having a second frequency, and mixes the first and second electrical signals to produce a third electrical signal having a third, sum or difference frequency. The third frequency represents a Doppler-shifted frequency caused by reflection of the first electromagnetic wave by a target at a distance from the Doppler radar unit. The test system converts the third electrical signal to a second electromagnetic wave having the third frequency, and transmits the second electromagnetic wave back to the Doppler radar unit for calculation of a speed representing that of the target as a function of the first and third frequencies, from which the Doppler radar unit may be calculated/certified.

Abstract: Embodiments of the invention provide apparatus (100) for detecting an erroneous measurement of a range of a target object 20 from a subject object 5. A transmitter transmits a signal (111S) having a first frequency from the subject object (5) to the target object (20). A detector (113) detects a portion of the signal (113S) reflected from the target object (20) back to the subject object (5); a controller is configured to determine the range (202) of the target object (20) from the subject object (5) by reference to a time of flight of the portion of the signal (111S), (113S) from the transmitter (111) to the detector (113); determine the rate of change of the range (203) by reference to a difference between the first frequency and an apparent frequency of the reflected portion of the signal (113S) detected by the detector; and provide an indication (206) that an erroneous measurement of range has been made if the range (202) increases while the rate of change of range (203) is negative.

Abstract: A method and system for estimating uncertainties in radar based precipitation estimates is provided. In an embodiment, gauge measurements at one or more gauge locations are received by an agricultural intelligence computer system. The agricultural intelligence computer system obtains precipitation estimates for the one or more gauge locations that correspond to the gauge measurements and computes the differences between the precipitation estimates and the gauge measurements. Using the precipitation estimates and the computed differences, the agricultural intelligence computer system then models a dependence of the uncertainty in the precipitation estimates on the value of the precipitation estimates. When the agricultural intelligence computer system receives precipitation estimates for a location where gauge measurements are unavailable, the agricultural intelligence computer identifies an uncertainty for the precipitation estimate based on the value of the precipitation estimate and the model of the dependence of the uncertainty on the precipitation estimate values.

Abstract: A probe (14) of a material level measuring apparatus (10) inserts into a container (20). The material level measuring apparatus (10) transmits an electromagnetic wave signal. When the electromagnetic wave signal touches a surface of a material (30), a first reflected signal is generated. When the electromagnetic wave signal touches a bottom of the probe (14), a second reflected signal is generated. According to the first reflected signal and the second reflected signal, a first time-passing difference value (t1) and a second time-passing difference value (t2) are obtained. According to the first time-passing difference value (t1), the second time-passing difference value (t2) and a predetermined empty container time-passing difference value (t3), a first material level and a second material level are obtained. According to the first material level and the second material level, a third material level is obtained.
