Abstract:
1. A radar system having an orthogonal antenna system, wherein said orthogonal antenna system comprises at least one transmit aperture producing a transmit beam and at least one receive aperture producing a receive beam, wherein said at least one transmit aperture is substantially orthogonal to said at least one receive aperture, wherein said transmit beam is narrow in a first dimension and wide in a second dimension, and said receive beam is wide orthogonally to said first dimension and narrow orthogonally to said second dimension, wherein a composite narrow beam cross-product results from an intersection of said transmit beam with said receive beam, and wherein said orthogonal antenna system, having a linear length of between 1.0 and 1.5 times that of a fully populated square 2D scan array, generates said composite narrow beam cross-product that is substantially the same resolution as said fully populated square 2D scan array.
