发明名称 Identifying obstacles in a landing zone
摘要 Mechanisms for identifying obstacles in a landing zone are disclosed. A first polarization elevation angle matrix is generated based on reflected radar signals having a first polarization sense. A second polarization elevation angle matrix based on reflected radar signals having a second polarization sense that differs from the first polarization sense is generated. The first polarization elevation angle matrix and the second polarization elevation angle matrix are integrated to form an integrated elevation angle matrix that identifies first scatterers and second scatterers with respect to the landing zone.

主权项 1. A method for identifying obstacles in a landing zone, comprising: generating, by a controller comprising a processor, a first polarization elevation angle matrix based on reflected radar signals having a first polarization sense, the first polarization elevation angle matrix corresponding to the landing zone and identifying an elevation angle of each of a plurality of first scatterers in the landing zone; generating a second polarization elevation angle matrix based on reflected radar signals having a second polarization sense that differs from the first polarization sense, the second polarization elevation angle matrix corresponding to the landing zone and identifying an elevation angle of each of a plurality of second scatterers in the landing zone; and integrating the first polarization elevation angle matrix and the second polarization elevation angle matrix to form an integrated elevation angle matrix that identifies the first scatterers and the second scatterers with respect to the landing zone.
