Abstract
A radar return channel is estimated at a radar receiver by processing an existing channel estimate along with a radar return signal for an ideal transmission, to produce an updated estimate. Updating can be carried out based on a determination that the existing estimate has become degraded. Embodiments include using a least squares deconvolution to update polynomials describing a transfer function of the channel estimate.
