  • Patent number: 12241971
    Abstract: Systems and methods relating to air traffic control and navigational aids for aircraft. An antenna system uses a multi-sector sensor that uses two vertical column antenna arrays per sector. Each pair of vertical column antenna arrays produces two beams that are off a boresight for each pair of antenna arrays. Wide angle monopulse processing is used to determine an azimuth or angle of arrival for an aircraft using at least one pair of the vertical column antenna arrays. Predetermined correction factors are applied to the azimuth for specific elevation values and, for elevation values without predetermined correction factors, interpolation between known predetermined correction values to arrive at the corrector factor to be applied.

  • Patent number: 11977145
    Abstract: Disclosed is a method and a corresponding distance-measuring device for measuring a distance to an object using FMCW radar. The method includes the frequency-dependent determination of the amplitude of the radar signal, i.e. the frequency response in the output path and in the input path of the distance-measuring device. The standard windowing of the evaluation signal can be corrected using a correction factor dependent on the frequency responses. Thus the frequency dependence of the radar signal is compensated independently of device-internal or external interferences by adapting the window function. The result is more accurate and reliable distance measurement using FMCW radar. Because the distance can be determined by the disclosed method very accurately and without distortion, it is advantageous to use the distance-measuring device as a fill-level measuring device to measure the fill level of a filling material in a container.

  • Patent number: 11762060
    Abstract: Techniques and apparatuses are described that implement height-estimation of objects using radar. In particular, a radar system, which is mounted to a moving platform, receives reflection signals that represent versions of a radar signal that are reflected off of objects. The radar system generates a range-elevation map based on raw data from the reflection signals, identifies an elevation bin and a range bin in the range-elevation map that corresponds to a selected object, and calculates a height for the selected object based on the range and elevation bins. The radar system then calculates a de-noised height for the selected object based on one or more previously calculated heights for the selected object. In this way, the radar system can determine accurate heights of objects at sufficiently long ranges for evasive action.

  • Patent number: 11668791
    Abstract: A simulation method for predicting a false positive for a predefined region outside a desired field of view of a radar sensor. Calculated primary rays having a respective primary energy level represent the radar signal. Reflected rays are calculated based on the primary rays or other reflected rays and based on geometrical data for at least one item within the predefined region. An energy level is determined for each reflected ray based on an estimated reflectivity of the at least one item and based on the primary energy level of the respective primary ray, and a clustering level for the reflected rays is determined based on distances of the respective reflection points. A probability for an occurrence of a false positive is estimated based on the energy level and the clustering level.
