Advanced Developments in Radar Technology Training Course Description

This three-day Advanced Developments in Radar Technology Training provides students who already have a basic understanding of radar a valuable extension into the newer capabilities being continuously pursued in our fast-moving field. While the Advanced Developments in Radar Technology Training course begins with a quick review of fundamentals – this to establish a common base for the instruction to follow – it is best suited for the student who has taken one of the several basic radar courses available.

In each topic, the method of instruction is first to establish firmly the underlying principle and only then are the current achievements and challenges addressed. Treated are such topics as pulse compression in which matched filter theory, resolution and broadband pulse modulation are briefly reviewed, and then the latest code optimality searches and hybrid coding and code-variable pulse bursts are explored. Similarly, radar polarimetry is reviewed in principle, then the application to image processing (as in Synthetic Aperture Radar work) is covered. Doppler processing and its application to SAR imaging itself, then 3D SAR, the moving target problem and other target signature work are also treated this way. Space-Time Adaptive Processing (STAP) is introduced; the resurgent interest in bistatic radar is discussed.

Customize It:

• We can adapt this Advanced Developments in Radar Technology Training course to your group’s background and work requirements at little to no added cost.
• If you are familiar with some aspects of this Advanced Developments in Radar Technology Training course, we can omit or shorten their discussion.
• We can adjust the emphasis placed on the various topics or build the Advanced Developments in Radar Technology Training course around the mix of technologies of interest to you (including technologies other than those included in this outline).
• If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the Advanced Developments in Radar Technology Training course in manner understandable to lay audiences.
