Radar
and Multi-Sensor Target Recognition
Instructor: Marvin N. Cohen,
USA
Synopsis:
In the introduction, the principles, motivations, and
terminology related to target recognition are presented
and discussed. Cooperative and traditional target recognition
methods are reviewed. The lecture continues with an in-depth
discussion of specific non-cooperative target recognition
techniques. The general relationships between radar parameters
and recognition functions are discussed. Underlying phenomenologies
and signal and identification processing techniques are
investigated and discussed in detail using the specific
examples of high-range-resolution-based aircraft identification
and Doppler-signature-based helicopter identification.
An overview of image-based radar techniques utilizing
SAR and ISAR is provided. The motivations for and potential
advantages of multi-sensor target recognition are presented,
as well as an overview of the principal issues related
to identification fusion system development. Thereafter,
a specific identification fusion algorithm is developed
and its performance is investigated. The lecture concludes
with a summary comparison of single-sensor, multi-mode,
and multi-sensor target recognition techniques. The particular
challenges and advantages of the approaches are compared
and contrasted.
