Dr. Harry Van Trees, the founder of our center, has recently published a second edition of his classic textbook in the field of signal processing, Detection, Estimation, an Modulation Theory, Part 1. According to reviews, the second edition is a thorough revision and expansion almost doubling the size of the first edition and accounting for the new developments thus making it again the most comprehensive and up-to-date treatment of the subject. With a wide range of applications such as radar, sonar, communications, seismology, biomedical engineering, and radar astronomy, among others, the important field of detection and estimation has rarely been given such expert treatment as it is in this text.
