Special signal processing techniques appended on to remote sensing capabilities are described for "peeking" inside "tel" cargos.

Multispectral analysis techniques permit analysis of nonlinearities giving rise to certain broadband signals. the advantages of this technique over linear methods are detailed.

Theoretical and practical capabilities of impulse radars are examined. enhancements to these impulse radars are shown to result in more powerful class of broad-band radars for practical target/ clutter discrimination.

There is a growing interest in the role of nonlinear signal proccessing (nsp) algorithms utilizing higher-order moments and higher-order spectral measurements for ferreting out information about unknown signals that are beyond the reach of linear techniques. nsp techniques dissect higher order… More

An innovative approach is proposed for the analysis of nonlinear and/or nonstationary signals and systems/sources that generate them. This approach is based on a canonical functional representation which yield multidimensional measurements of the nonlinear and/or nonstationary characteristics and… More

The key to enhanced detection performance of future active ASW sonar systems is the suppression of heavy clutter present in projected areas of operation (e.g., littoral waters). Although improvements can be made in many operational aspects of future systems, the fundamental limitation in performance… More

Not Available It is proposed to design and build a low mass, low power, low cost, high temperature furnace for use in space. Vacuum and radiation insulation provide a means to almost eliminate heat losses from the furnace, allowing high temperatures to be achieved using low power. A cylindrical… More
