System Design Considerations for Decision-Theoretic Antenna Processing Systems,

Abstract : The functional design of a decision-theoretic adaptive radar (DTAR) is outlined with a comparison among scanning, multiple-beam, and parallel-antenna-element transmitting and receiving systems. Decision-theoretic antenna processing is operationally contrasted with conventional processing. The performance of DTAR is evaluated for single-target detection and estimation and contrasted with the performance of conventional processors. Average Bayes risk is used as a performance criterion. The multiple-target hypothesis testing and estimation problem is formulated and solved for a uniform clutter environment. A suboptimum estimator is developed to ease computational difficulties. A simplified decision tree is developed and proved optimum. Range and velocity measurements are designed by analogy with antenna array theory. A frequency-sampling coherent radar results. (Author)
