Book Description
A reference source for phase noise effects on systems and components. Analyzes the effects of phase noise on a radar system's performance and on its major subsystems. Sequence of chapters follows the path of phase noise in a radar system from its generation through its transmission, reception, and processing to its final displayed level. Discusses major radar design areas pertaining to the analysis of phase noise effects on system performance. Includes solved practical problems and computer programs.

Book Description
In today's world, the range of technologies with the potential to threaten the security of U.S. military forces is extremely broad. These include developments in explosive materials, sensors, control systems, robotics, satellite systems, and computing power, to name just a few. Such technologies have not only enhanced the capabilities of U.S. military forces, but also offer enhanced offensive capabilities to potential adversaries - either directly through the development of more sophisticated weapons, or more indirectly through opportunities for interrupting the function of defensive U.S. military systems. Passive and active electro-optical (EO) sensing technologies are prime examples. Laser Radar considers the potential of active EO technologies to create surprise; i.e., systems that use a source of visible or infrared light to interrogate a target in combination with sensitive detectors and processors to analyze the returned light. The addition of an interrogating light source to the system adds rich new phenomenologies that enable new capabilities to be explored. This report evaluates the fundamental, physical limits to active EO sensor technologies with potential military utility; identifies key technologies that may help overcome the impediments within a 5-10 year timeframe; considers the pros and cons of implementing each existing or emerging technology; and evaluates the potential uses of active EO sensing technologies, including 3D mapping and multi-discriminate laser radar technologies.

Book Description
This book develops the principles and practice of laser radar system design by examining sensor technology across the entire electromagnetic spectrum. This new book discusses the similarities and differences between microwave and optics technologies. It combines a microwave radar system treatment of the range equation, target cross-section and measurement principles with an optical receiver discussion which illustrates differences in system noise mechanizations. The presentation also includes theoretical and hardware considerations which illustrates systems utilized to provide altimetry, rangefinding, target designation and imaging, as well as laser radar systems providing instantaneous six-dimensional target information.

Book Description
Experiments with a CW, random-noise, X-band, radar ranging system are presented, following the technique proposed and used by G.L. Poirier. The correlation signal-processing method differs from that of other noise radars in that no delay lines are required. The signal-processing technique also decorrelates clutter and other interference, including the transmitted signals of other radar systems identical except for their statistically independent noise sources. An application to small-vessel navigation systems is proposed. Other applications in communications and jamming systems are considered. The experiments verify a ranging accuracy of 1.45 meters at a range of 154 meters. The range capability extends from a minimum of 30 meters to the radar horizon at 19,000 meters in the system constructed. The minimum range and accuracy capabilities exceed those of existing pulsed radars installed in small craft. Possible solid-state implementations using currently available devices are outlined. Proposals for future experiments are made, including shortening of minimum range by increasing transmitted bandwidth, and increasing accuracy by refinement of the laboratory model. (Author).
