COURSE # ROO-431
RADAR CROSS-SECTION MEASUREMENT, EXPLOITATION AND COHERENT SIGNAL PROCESSING
An in-depth treatment of radar concepts and techniques used for low-observable target detection and classification.
Modern targets effectively reduce their observability features applying new material technologies and employing cover, concealment, and deception to deny acquisition. Consequently, modern radar systems employing sophisticated signal processing must keep up with the new scenarios through exploitation of target features revealed only by precision measurements. This course addresses the interpretation of radar signatures data for extraction of maximum information from radar returns. Actual target and clutter signatures data are used to illustrate how advanced radar processors perform surveillance, detection, discrimination, and non-cooperative target identification functions.
In addition, this course provides a basic understanding of radar and signal processing technologies used for cooperative target RCS measurements and tactical engagements. Practical concepts for interpretation and utilization of Radar Cross Section data are developed based on RCS versus aspect, Doppler signatures, high-resolution imagery, and polarimetric signatures. Target sets examined include fixed- and rotary-wing aircraft, missiles, periscopes, ships, and wakes.
Applications and benefits:
You will benefit by enhancing your understanding of the:
- Radar technology and target discrimination principles.
- Interpretation of static and dynamic target radar signatures with emphasis on signal processing.
- Correlation of radar signatures with target features and comparison of data sets processed by different methods.
- Evaluation of radar target engagement scenarios.
- Effects of radar system parameters, signal processing parameters, and of the environment on observed target characteristics.
- Practical techniques to exploit target features for discrimination and identification.
Who should attend:
Weapon system acquisition executives, management, engineers and scientists involved in survivable platform design or radar system development and upgrade; engineers and technicians involved in radar cross section measurements; and data interpretation, and digital signal processing engineers. There is no prerequisite for this course; however, a familiarity with electromagnetic waves and radar principles will be helpful.
