A block lattice MTI system compatible with stagger-period emission

Based on the criterion of minimum mean square prediction errors for stagger-period sequences, this paper presents a new structure of a staggered lattice predictor. By means of the methods and theories of uniform lattices, operational expressions, optimality theory and algorithms of reflection coefficient estimation of the stagger-period type lattices are researched, and the learning characteristics of block lattices in stationary and nonstationary sequences discussed. Some heuristic strategies for preserving targets and rejecting false alarms are based on practical experiences of many radar experts and are achieved with a number of inference rules. Simulation tests of an MTI system which utilizes a staggered block lattice filter are given, and good performances of clutter suppression and target detection are shown
