摘要： The antenna uses X Band frequencies for long-distance weather monitoring and W Band frequencies for imaging of terrain and obstacles, for use in a radar system in aircraft nose radome to operate effectively in a degraded visual environment. The antenna's feed structure includes concentrically positioned first and second horns. First and second rectangular waveguides are positioned on a cylindrical portion of the first horn, and at a first and second radial positions spaced 90 degrees apart. First and second coaxial cables respectively couple the first and second rectangular waveguides to a polarization converter, which launches linearly polarized waves received from each of the first and second coaxial cables to form a W-hand circularly polarized wave. The feed structure collects and disseminates W Band and X Band electromagnetic energy.

摘要： In a radar device, a reception antenna directly receives a chirp signal transmitted by a transmission antenna of a module other than a module to which the reception antenna belongs among a plurality of modules, a mixer generates a baseband signal by mixing a chirp signal generated by a chirp signal source and a chirp signal received by the reception antenna, and an analog-to-digital converter generates a digital signal by digital-converting the baseband signal generated by the mixer.

摘要： An image generating device for a radar includes a receiving module configured to receive a radar signal from an antenna and process the radar signal to generate an echo, an edge image generator configured to generate an edge echo image based on the echo acquired at a first time instance, a projected image generator configured to generate a projected echo image based on the echo acquired at a second time instance, and a superimposition generator configured to superimpose the edge echo image on the projected echo image based on the first and second time instances, to generate a superimposed echo image.

摘要： In one aspect, a system for determining subsurface soil layer characteristics as an agricultural implement is towed across a field by a work vehicle may include a RADAR sensor configured to capture data indicative of a subsurface soil layer characteristic of the field. Furthermore, the system may include a load sensor configured to capture data indicative of a load applied to the agricultural implement by soil within the field, with the load being indicative of the subsurface soil layer characteristic. Additionally, a controller of the system may be configured to determine a first value of the subsurface soil layer characteristic based on the data received from the RADAR and a second value of the subsurface soil layer characteristic based on the data received from the load sensor. Moreover, the controller may be configured to determine a differential between the first value and the second value.

摘要： A method for producing an interference reduced radar image comprises receiving a measured sequence of beat signals; identifying one or more interference segments within the measured sequence of beat signals, an interference segment being a segment subject to an interference; doctoring the measured sequence of beat signals by creating a doctored representation of the measured sequence of beat signals in the form of a matrix Y; creating a doctoring mask representing the doctoring of the measured sequence of beat signals, the doctoring mask being a matrix M; and estimating a reconstructed range-doppler image {circumflex over (X)} from Y and M, wherein the reconstructed range-doppler image is a range-doppler image of Y which is deconvolved using M; such that doctoring the measured sequence of beat signals at least partially removes interference effects and estimating a reconstructed range-doppler image at least partially removes image artefacts created by the doctoring.

摘要： Techniques are provided for determining a location of a mobile device based on visual positioning solution (VPS). An example method for determining a position estimate of a mobile device includes obtaining sensor information, detecting one or more identifiable features in the sensor information, determining a range to at least one of the one or more identifiable features, obtaining coarse map information, determining a location of the at least one of the one or more identifiable features based on the coarse map information, and determining the position estimate for the mobile device based at least in part on the range to the at least one of the one or more identifiable features.

摘要： A multiple input multiple output imaging array for incident angle resolved images with respect to a device under test is provided. The multiple input multiple output imaging array comprises a redundant array of transmit and receive antennas and a controller. In this context, the controller is configured to implement a selection scheme, wherein the selection scheme selects the respective transmit and receive antenna pairs used to create the corresponding image.

摘要： An inspection system uses radio waves to inspect the state of an object at low cost and efficiently, the foregoing possible as a result of the system comprising: a measurement unit that measures reflected waves from an object making a prescribed movement, the waves having been generated by projecting radio waves to the object; a moving body that comprises the measurement unit and moves so that the relative positional relationship between the measurement unit and the object changes with the passage of time; and a generation unit that generates information representing the state of the object by performing signal processing on a signal indicated by the reflected waves.

摘要： The present invention provides an abnormality diagnosis system capable of improving reliability of a diagnosis result on a state of a detector mounted to a vehicle.
An abnormality diagnosis system (50) that diagnoses abnormality of a detector (20) detecting surrounding information on the vehicle includes: a positioning device (59); a storage device (55) that stores map data (70) containing data on an object existing on/above the ground; and a control section (51) that diagnoses presence or absence of the abnormality of the detector (20) by comparing the map data (70) with detection data obtained by the detector (20).-
