KB-MTD Schemes against Joint Extended and Discrete Clutter for Ground-Based Radars

The paper considers various MTD schemes against the additive background mixture of a range-extended and range-discrete clutter, which implement the knowledge-based (KB) methodology with different efficiency. The analysis and results of their quantitative comparison in a hypothetical situation of known parameters of Gaussian input data are given. On the basis of these results, KB-MTD systems, which are suitable for use in real conditions of a priori uncertainty of the parameters, are substantiated.
