Principles of Radar and Sonar Signal Processing (Artech House Radar Library (Hardcover))

A radar or an active sonar is a system that transmits a wave of known shape and receives the echoes returned by different obstacles or targets in the landscape. Content: 1. Radar and Sonar -- 2. Optimum Reception in White Noise -- App. 2A. Cramer-Rao Equality -- 3. Application to Radar -- App. 3A. Relation Between the Duration and Bandwidth of a Signal -- App. 3B. Radar Range Equation -- App. 3C. Spectral Purity -- 4. Optimum Reception in Colored Noise -- App. 4A. Karhunen-Loeve Expansion -- App. 4B. Optimum Receiver in Colored Noise -- App. 4C. Estimation of a Random Signal in the Presence of White Noise -- Wiener-Hopf Equation -- 5. Adaptive Processing -- App. 5A. Matrix Inversion Lemma -- 6. Target and Background Signatures -- App. 6A. A Multifrequency Ground Clutter Model -- 7. Signature Adapted Processing -- App. 7A. Variance of a Rayleigh Variable at the Output of a Logarithmic Amplifier. This work covers the latest technologies in conventional and adaptive signal processing theory, and covers techniques for detailed analysis of physical signatures of targets and clutter. Examples of signatures offer greater insight into classification problems. A discussion on low frequency systems, wideband radars, and STAP (space-time adaptive processing) provides practitioners with a better awareness of physical limits and future developments.
