National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Multi-Aspect Radar Algorithms (MARA) Study.

ADA510305

Publication Date	2009
Page Count	44
Abstract	Sci-Teq, Inc. submits this report as the third quarterly report on the 18 month study entitled 'Multi-Aspect Radar Algorithms (MARA)'. The MARA study is investigating and defining a surveillance system concept for a net- sentric surveillance sensor system. The system will be comprised of multiple, geographically dispersed, multi-band, multi-static Inverse Synthetic Aperture Radar (ISAR) imaging sensors with co-located ESM sensors. The operational objective of these multi-sensor net-worked systems is to provide area surveillance of maritime traffic with an inherent classification/identification capability through the use of multi-static radar image generation augmented with electromagnetic signature detection and correlation. The networked surveillance system concept would be implemented using a COTS line-of-sight wireless network and GPS time to coherently synchronize and event-time the sensors operating on the network when conducting multi-static data collection and generation. The research study is defining and evaluating algorithms for the generation and processing of the multi-aspect ISAR data from the multi- static radar systems operating within the network. The research study is also investigating and defining an architecture and design for a data collection radar system to be implemented with COTS subsystems. The network will serve to time synchronize and control the operations of the multi-static radars during multi-static data collection testing and operations. The MARA project studies will also define a system of AESA based radars and Electronic Support (ES) surveillance (ES) sensors that could form an operational sensing network capable of surface surveillance coverage to the horizon, image-while-search, and independent or unified ISAR operations. All systems operating within the network will be phase-locked and time synchronized and will provide all radar imagery and corresponding ESM intercept information to all units on the network.
