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 &thetas;1 relative to the boresight axis and the other transmitting antenna may be squinted at an angle of &thetas;2 relative to the boresight axis in a second dimension. The transmitting antennas are not squinted relative to one another in the first dimension.
