摘要： The invention relates to a method for spectral estimation of the clutter of a haline liquid medium received by an oceanographic radar, such as a lake, a river, a sea or an ocean, from an array of antennas including at least three antennas. The method includes the following steps: a first step (101) of forming at least two sub-arrays of antennas from the array of antennas, each of the sub-arrays including at least one antenna less than the array of antennas; a second step (102) of calculating a beam in one direction for each sub-array of antennas; a third step (103) of locating in azimuth all the sources comprised in the beam from data of the beam coming from each of the sub-arrays; a fourth step (104) of estimating the energy of each of the located sources; and a fifth step (105) of selecting a source, referred to as preferred source, among a plurality of sources according to a predetermined criterion when the beam includes a plurality of sources.

摘要： This disclosure is directed to methods, devices, and systems for generating a weather radar output with bright band suppression. In one example, a method includes determining, for each of several portions of a vertical column from a weather radar signal, a reflectivity range selected from a highest reflectivity range and one or more lower reflectivity ranges. The method further includes determining, in response to determining that portions of the vertical column are in the highest reflectivity range, whether a combination of the reflectivity ranges of the portions of the vertical column meet criteria indicative of high-reflectivity stratiform weather. The method further includes generating, in response to determining that the combination of the reflectivity ranges of the portions of the vertical column meet the criteria indicative of high-reflectivity stratiform weather, a weather radar output that indicates each of the portions of the vertical column as associated with one of the lower reflectivity ranges.

摘要： In some examples, a radar system is configured to mount on an ownship vehicle for interleaving a weather detection mode and an object detection mode. The radar system comprises a phased-array radar device configured to receive weather signals in the weather detection mode, receive sensing signals in the object detection mode, and interleave the weather detection mode and the object detection mode. The radar system further comprises processing circuitry configured to determine weather conditions based on the received weather signals and detect an object based on the received sensing signals.

摘要： A three-dimensional wind vector field measurement system employs convergent beams for localised velocity measurement enabling mapping of the wind field across an extended spatial region. This enables characterisation of complex field signatures. This enables advanced control and protective systems for wind turbines. This also enables improved wind harvesting. This also enables improved prospecting. This also enables improved equipment selection. Buoy mounted systems enable measurement in an offshore environment.

摘要： A method may include generating for transmission a repeating sequence of N constant-frequency pulses of width t seconds at interpulse intervals of T seconds, with each pulse in the sequence having a particular constant phase according to a quadratic phase sequence, which phase is applied to each pulse in a first sense of modulation. The method may further include modulating the phase of echo energy received from one or more objects reflecting the transmitted repeating sequence of N constant-frequency pulses with a second sense of modulation opposite to the first sense of modulation. The method may further include producing from the modulated received echo energy N unique and discrete frequency translations of the received echo energy as a function of range r of the reflecting objects, of magnitude equal to multiples of 1/NT Hz, which may preserve the spectrum of the received echo energy, forming in combination a composite signal frequency spectrum.

摘要： Embodiments provide methods, systems, and/or devices that can provide measurements of the inherent reflectivity distribution from different look angles using N radar nodes. Doppler weather radars generally operate with very good spatial resolution in range and poor cross range resolution at farther ranges. Embodiments provide methodologies to retrieve higher resolution reflectivity data from a network of radars. In a networked radar environment, each radar may observe a common reflectivity distribution with different spreading function. The principle that the underlying reflectivity distribution should remain identical for all the nodes may be used to solve the inverse problem to determine intrinsic reflectivities.

摘要： Apparatus and associated methods relate to determining, based on a detected portion of a projected pulse of quasi-optical energy backscattered by water particles within a divergent projection volume of a cloud atmosphere, properties of the backscattering water particles. The pulse of quasi-optical energy is projected into the divergent projection volume of the cloud atmosphere (12). The divergent projection volume is defined by an axis of projection and an angle of projection about the axis of projection. The portion of the projected pulse of optical energy backscattered by water particles within the divergent projection volume of the cloud atmosphere is received and detected. Various properties of the backscattering water particles, which can be determined from the detected portion of the projected pulse backscattered by water particles can include particle density and/or particle size.
