Watch AESS educational video tutorials

31 May 2015 - 10:00

The IEEE Aerospace and Electronic Systems Society (AESS) has made available a series of free educational video tutorials, which are available on demand. Registration is open to all AESS members. Send an email to Judy Scharmann (j.scharmann [at] conferencecatalysts.com) to request access.

You can find out more about the video tutorials here: http://evts.ieee-aess.org/

Here is a list of the available tutorials:

Bistatic & Multistatic Radar – Hugh Griffiths

Bistatic radar has a long history, dating back to the earliest days of radar. It is presently the subject of expanded interest, and new systems are now being designed and evaluated, for applications including SAR and GMTI surveillance from UAVs, air defense and counter-stealth. Of particular current interest is Passive Bistatic Radar, using broadcast, communications or radio navigation signals as the illumination sources.

The tutorial, presented by one of the editors of the recently-published book ‘Advances in Bistatic Radar’, provides an introduction to the fundamentals of bistatic radar, showing how the properties depend on the bistatic geometry. This is followed by a more detailed description of the subject of Passive Bistatic Radar and of Bistatic SAR. Examples of a number of practical systems and their results are given and discussed.

GPS/GNSS + Inertial Navigation – James Farrell

IEEE-AES is disseminating information to people in the profession, providing a foundation of understanding to make up for attrition as experts retire and become unavailable. As part of this IEEE program, this presentation focuses on two pervasive areas of navigation – inertial (Part One) and satellite-based (Part Two).

For brevity, the presentation emphasizes main points, with the understanding that available references show adjustments to provide all needed refinements. Although the main emphasis is on fundamentals, some advanced concepts are included too. For example, the flight results discussed were achieved by using 1-second sequential changes in GPS carrier phase for dead reckoning only. This immediately eliminated three fundamental major vulnerabilities present in conventional usage of carrier phase. In addition, attention is drawn to motion-sensitive errors of inertial instruments. Unaided operation, that is, “free-inertial” navigation — without correction via GPS or other measurements — is also described.

Radar System Performance Modeling – G. Richard Curry

This course provides and explains equations, computational methods and data for modeling radar performance at the system level, and provides insight on how to use the models in system analysis. It is intended for system analysts involved in analyzing systems that include radars, modelers and programmers involved in simulating performance of radars in systems, and radar system analysts and designers.

Specific topics covered include: Introduction to radar modeling, radar analysis parameters, radar waveforms, the radar equation, radar detection, radar search, radar measurement and tracking, radar environment and mitigation techniques, and lastly, radar countermeasures and counter-countermeasures.

Sea Clutter – Simon Watts & Keith Ward

The understanding and modelling of radar sea clutter is central to the design and performance evaluation of radars in a maritime environment. The first part of the tutorial will introduce the methods used to describe radar sea clutter and show how physical and empirical models are developed.

The second part of the tutorial will show how clutter models are used to predict performance and analyse the performance of CFAR detection systems. This will concentrate on the application of the compound K distribution sea clutter model.

Specific topics covered include: The observed characteristics of sea clutter, statistical models of sea clutter, modelling radar scattering from the ocean surface, detection performance calculations, cell-averaging Constant False Alarm Rate (CFAR) performance in sea clutter, adaptation to changing clutter PDF, and practical CFAR systems.

Fundamental Concepts in Radar Signal Processing – Mark A. Richards

Modern radar signal processing is a broad and increasingly sophisticated field, but many of the most important techniques are based on a few fundamental concepts such as signal phase structure modeling, coherent integration, matched filtering, bandwidth-resolution relationships, maximum likelihood estimation, and modeling of interference statistics.

This tutorial reviews the core techniques of pulse compression, Doppler processing, adaptive beamforming, imaging, constant false alarm rate detection, and estimation with an emphasis on highlighting their common reliance on these fundamentals.

Introduction to Stealth – David Lynch

This tutorial covers a broad range of issues related to the application of signature reduction, both active and passive, to improved mission survivability. Stealth for surface and airborne platforms is addressed.

Specific topics covered include: active and passive signature notions, radar/ladar cross section, materials and shaping, dihedrals, edge treatment, Radiation Absorbing Materials (RAM), and Circuit Analogs (CA) to bulk materials.
