Past Lectures

Past, Present and Future of Secondary Radar
Ed Gellender - Northrop Grumman
2014 July 2

A historical review and a discussion on the anticipated future of SSR/IFF, puts this subject into perspective. Time-tested legacy techniques are explored, as well as some of the most recent technologies. Specific topics covered include IFF antenna patterns, frequency and spectrum usage, civil air traffic control, military command and control (including Mode 5), new collision avoidance systems, and FAA NextGen air traffic control.

Remote Sensing Principles and Applications, Part I
Daniela Viviana Vladutescu - NYCCT/CUNY
2013 October 2

Todayís remote sensing activities can broadly be subdivided into active and passive remote sensing from the Earth's surface and/or from satellites. Active collection emits energy in order to scan objects and areas whereupon a sensor then detects and measures the radiation that is reflected or backscattered from the target. RADAR is an example of active remote sensing where the time delay between emission and return is measured, establishing the location, height, speed and direction of an object. In passive remote sensing, the source of information is scattered and/or absorbed solar and emitted thermal radiation that allows clues on climate system components through their spectrally variable response.

In terms of observation platforms satellites provide valuable opportunities for collecting global fields of many climate system variables. Airborne field measurement campaigns offer an adequate opportunity to develop new remote sensing algorithms and to define demands of new satellite missions. In addition, surface based measurements allow better controlled and temporally higher resolving measurements, especially of boundary layer and lower atmosphere quantities. Several of these "new" observing systems are now developed into reliable systems for routine standard observations, that are more and more recognized as valuable tools for the observation of relevant climate processes on various scales in time and space, space surveillance and target detection.

National Missile Defense
Larry Chasteen - Distinguished Lecturer of the AESS
2006 October 12

The United States Government (Bush Administration) made major changes to the limited National Missile Defense (NMD) system that was proposed earlier by the Clinton Administration. Even with the new national emphasis on anti-terrorism and closer relations with Russia, NMD is still a very controversial topic as seen with the recent US proposal to withdraw from the Anti-Ballistic Missile (ABM) treaty. The NMD program will continue to be a key technical, political, and legislative issue facing the U.S. and the rest of the world. The Bush Administrationís NMD program focuses more on testing and developing new parts to the NMD system. The NMD system will still operate as an integrated system but will investigate a wider variety of sensors (such as space-based and sea-based) to detect and track incoming missiles. The upgrade to the existing Early Warning Radars (EWR) is one of the few features that has not changed from the proposed Clinton plan. This talk will provide background and technical information on the upgrades to the EWRs. The talk will also provide program and system engineering details on the new proposed testing of the total NMD system.

Multisensor Data Fusion
Pramod Varshney - Distinguished Lecturer of the AESS and IEEE Fellow
2004 November 15

Multisensor data fusion refers to the acquisition, processing and synergistic combination of information gathered by various knowledge sources and sensors to provide a better understanding of a phenomenon. It is a fascinating and rapidly evolving field that has generated allot of excitement in the research and development community. These concepts are being applied to a wide variety of fields such as military command and control, robotics, image processing, air traffic control, medical diagnostics, pattern recognition, and environmental monitoring. This talk presents a brief overview of the field and illustrates its potential by means of some examples. In addition, current research activity in the areas of distributed radar target detection and recognition, distributed sensor networks, image fusion, and visualization are described.

Target Tracking & Data Fusion: Get the most out of your sensors
Yaakov Bar-Shalom - Distinguished Lecturer of the AESS and IEEE Fellow
2004 October 4

This lecture describes the evolution of the technology of tracking objects of interest (targets) in a cluttered environment using remote sensors. Approaches for handling target maneuvers (unpredictable motion) and false measurements (clutter) are discussed. Advanced ("intelligent") techniques with moderate complexity are described. The emphasis is on algorithms which model the environment and the scenarios of interest in a realistic manner and have the ability to track low observable (LO) targets. The various architectures of information processing for multi-sensor data fusion are discussed. Applications are presented from Air Traffic Control (data fusion from 5 FAA radars for 800 targets) and underwater surveillance for an LO target.

Myron Kayton - Distinguished Lecturer of the AESS and IEEE Fellow
2003 November 20

The lecture will consist of a navigation overview; the characteristics of navigation systems for aircraft, automobiles, ships and spacecraft; coordinate frames; absolute navigation versus dead reckoning; time measurement; GPS and Differential GPS; testing; animal navigation; and the future of navigation.

From Goddard to Apollo
Burton Dicht - ASME
2003 October 16

With the recent loss of the Shuttle Columbia and its crew, Americans have turned their attention toward NASA and the human space flight program. For more than forty years, American and International astronauts have rocketed their way into space and beyond. During the more than 140 US space flights, NASA has experienced great triumph, failure and devastating tragedy. This presentation will focus on perhaps NASA's greatest triumph, the landing of Americans on the moon. It has been more than thirty years since Neil Armstrong and Buzz Aldrin landed their Lunar Module "Eagle" on the lunar surface culminating one of the greatest explorations in human history. Project Apollo was the largest peacetime engineering project ever undertaken by the United States. At its peak it involved more than 20,000 companies and 400,000 people.

It was a remarkable technological achievement that was born out of the Cold War. Mr. Dicht's presentation will trace the history of America's race to the moon, from its simple origins of a 15 minute sub-orbital flight to the triumph of six successful moon landings. Starting with Robert Goddard and his early experiments with rocketry, thru War World II, and finally to Sputnik and Project Mercury, Mr. Dicht will discuss how America harnessed its technological resources to meet President Kennedy's challenge. Mr. Dicht will also touch on the recent tragedy and what the future might hold for NASA and America's space program.
