PP )T , the Cram´er–Rao bound of the parameter pk is given by the inequality Updated QR Decomposition Given the QR decomposition Z = LQ of the radar data matrix Z = (z1 z2 ··· zK ), it is sometimes necessary to update the matrix L if another measurement zK+1 is appended to Z, or if the measurement z1 is deleted. This need arises when the trainig data are collected from a sliding range window around the rangegate of interest, perhaps with a few guard ranges deleted near this target range. As the radar steps through each rangegate looking for the presence of a target, radar data are added to the front of the training window and deleted from the rear.
Because ground clutter has a spatiotemporal dependence—clutter to the front of the aircraft has a positive Doppler shift and clutter to the rear has a negative shift—a two-dimensional ﬁlter utilizing both these dimensions is required. Such a ﬁlter is obtained from the adaptive weight vector w = R−1v of Eq. (72) if v is a space–time steering vector of the form described above in the sub-subsection on that subject and R is a space–time covariance matrix of the form described in the subsection “Noise, Jammer, and Clutter Covariance Matrices” above.
