TWO-CHANNEL MONOPULSE RADAR FOR THREE-DIMENSIONAL DETECTION

摘要

An apparatus for determining the position of a target object using a two-channel monopulse radar. The radar may include two transmitting antennas and one common receiving antenna disposed in a coplanar arrangement. The transmitting antennas may be positioned on the focal plane of the radar along a focal plane axis that extends through, and that is perpendicular with, a boresight axis of the radar. The transmitting antennas may be spaced apart from one another in a first dimension a distance equal to about one half of one wavelength of the radar's center operating frequency. One of the transmitting antennas may be squinted at an angle of θ1 relative to the boresight axis and the other transmitting antenna may be squinted at an angle of θ2 relative to the boresight axis in a second dimension. The transmitting antennas are not squinted relative to one another in the first dimension.
