The paper determines the parameters of a coherent pulse-burst integrator with multi-channel capabilities interms of velocity and acceleration. We indicate the singularities of the pulse burst ambiguity function in the velocity-acceleration plane. We present algorithms for estimating velocity and acceleration. We propose a system for multi-channel matched filtering of an unmodulated coherent pulse burst with preliminary non-coherent integration, using which significantly reduces computational expenses. We determine the conditions that lead to the system exhibiting no threshold signal loss.
