For this Phase I effort, Observera proposes to develop an attribute based system for automated image quality assessment of Synthetic Aperture Radar (SAR) Imagery. Observera's expertise in SAR image analysis, image quality assessment and digital image processing algorithms are uniquely suited to this program. The imagery community uses the Radar National Imagery Interpretation Rating System (RNII ...

A demonstration of Broadband Code Division Multiple Access (CDMA) for PCS communications overlaid in the 800 MHz AMPS cellular band will be conducted. Broadband CDMA using direct sequence spread spectrum has significant military advantages of jamming immunity and low probability of intercept. It is also the most promising of the new concepts for high capacity commercial cellular radio because of ...

The program objective is to develop novel designs, techniques, and structures to synthesize apertures capable of efficient operation over broad frequency ranges and functions. Conventional apertures are narrowly focused, application specific, and basically single point design. To decrease the cost of antennas, a more universal building block design is required. It would provide a significantly ...

We propose a plan sentinel prototype consisting of three components. The first component is the development of a plan mining tool which identifies and computes false or missing assumptions and deviations to plans and time phased tasks. The second component, the annotated database, computes plans which the plan mining tool access and parses into a logical annotated rule set. Finally, MAVIS, a to ...

THIS PROPOSAL INVOLVES THE DEVELOPMENT OF TECHNIQUES FOR AUTOMATED PROCESSING OF SNYTHETIC APERTURE RADAR (SAR) IMAGERY. SPECIFICALLY, THIS TASK INVOLVES FINDING ALTERNATING CURRENT (AC) POWER LINES AND RELATED STRUCTURES FROM HIGH-RESOLUTION AIRBORNE SAR (ASAR) IMAGES. WE WILL IDENTIFY AREAS FOR IMPROVEMENT AND DEVELOP NEW TECHNIQUES AS NECESSARY TO STRENGTHEN WEAK AREAS. WE WILL ESTABLISH A METH ...

RECENT TREATY NEGOTIATIONS BETWEEN THE US AND THE USSR PLACE LIMITS ON THE SIZE AND LOCATIONS OF NUCLEAR TESTS. THESE LIMITS ARE PERCEIVED AS POTENTIAL INDUCEMENTS FOR THE USSR TO CONDUCT HIDDEN TESTS OUTSIDE THE TREATY REQUIREMENTS. ONE METHOD OF SECRETLY CONDUCTING TESTS WOULD BE TO PERFORM DECOUPLED TESTS IN LARGE HIDDEN UNDERGROUND CAVITIES. THE US MUST BE PREPARED TO QUICKLY AND EFFECTIVELY I ...

Improved magnetic and electromagnetic sensors covering a wide range of frequencies, 0 to 10kHz, and with extremely high sensitivity are proposed for broad area detection and characterization of underground targets. The sensors can be used for a variety of applications and for different e.m. sources. They can be configured as gradiometers, as vector or scaler sensors and can be used as internette ...
