Projection of the
Cross-Ambiguity Function
Signal Lab's Projection
capability yields the Radon
Transformation of the of the Cross-Ambiguity
Function (CAF), in a
computationally efficient manner. Where the Radon Transform first
requires the computation of the CAF, which is an Order N2LOG2(N)
process, Signal Lab's
Projections reduce the total computational requirements to an Order NLOG2(N) process.
Signal Labs' Projections enable quick
identification of target peaks within the CAF. Projections
of the CAF can be performed at any
angle. The projection angle is typically matched to the specific
Radar waveform utilized for optimal detection performance. As an
example, a projection of the CAF onto the Doppler axis (angle =
PI/2) is shown in Figure
1 below.
