Space-Time Adaptive Processing (STAP) refers to a class of signal processing techniques used to process returns of an antenna array radar system. It enhances the ability of radars to detect targets that might otherwise be obscured by clutter or jamming.

. The output of STAP is a linear combination or weighted sum of the input signal samples .The “adaptive” in STAP refers to the fact that STAP weights are computed to reflect the actual noise, clutter and jamming environment in which the radar finds itself. The “space” in STAP refers to
the fact that STAP the STAP weights (applied to the signal samples at each of the elements of the antenna array) at one instant of time define an antenna pattern in space. If there are jammers in the field of view, STAP will adapt the radar antenna pattern by placing nulls in the directions those jammers thus rejecting jammer power. The “time” in STAP refers to the fact that the STAP weights applied to the signal samples at one antenna element over the entire dwell define a system impulse response and hence a system frequency response.

Seminar Presentation Outline

Ambient intelligence (AmI) refers to electronic environments that are sensitive and responsive to the presence of people.

Intelligent User Friendly Interfaces

Better integration of technology into our environment, so that people can freely andinteractively use it.
Business Models for AmI

Seamless (and secure) delivery of services and applications
Current Reserch
Advantages Of Ambient Intelligence.
Future Scopes of Ambient Intelligence Technology.
Conclusion...

Seminar Guidlines Added in PPT File

AMI points to digital environments that includes real life.

To be short. This interface provides greater scope for

intrgrating latest technology with our day to day lives...

Let us have a look at the System Architecture,

We have the user who inputs data or requires

some process to be completed. The trusted context

server contains the information required for the

processes to be completed as per needed.

This context is in high level language and needs

to be converted….This is done by the domain

specific who corresponds with the user as well.

The domain specific agent translates the high

level mesges into ebXML msges and feeds it inot the registry.
