Decentralised detection systems with parallel decision fusion topology have received significant attention, especially for surveillance radar systems. Typically, a deterministic test (DT) is employed, and the optimal local strategies rule are determined according to Neyman–Pearson (N–P) criterion. The authors show how, in practical applications, communication bottle-neck may significantly limit performance of distributed employing conventional DT. A paradigm introduced decentralised under constraints, based on concept dependent randomisation (or scheduling) rules. Numerical results that proposed approach provides improved over tests, moderate increase system complexity; improvement particularly noticeable spiky (non-Gaussian) clutter environments.
