Radar signature analysis of targets

Recognition and classification


This training will enable engineers who are already familiar with the operation of the radar:

  • to learn the technical analysis of targets radar signature, and discover the technology to adjust these particular signatures for stealth or deception purposes,
  • to strengthen their skills in the field of recognition and identification by the presentation of the latest techniques.

This course takes into account the effects of clutter within these two aspects.


The course lasts 5 days (33 hours) and includes:

  • 18 lectures of 1:30
  • 2 tutorial sessions
  • 1 visit of radar signatures facilities


The course brings together manufacturers of discrete targets, radar operators and specialists of recognition and identification. The former are concerned with building low detectable targets, taking into account both the properties of the target and the clutter. The second perfect radars and associated tools for reconnaissance and target identification, including reduced or controlled signature targets and also taking into account aspects of clutter.

Teaching is presented so as to convey the principles and existing tools and recently studied in two closely related areas that are :

  • control of the targets radar signature using both experimental and theoretical calculations
  • recognition and identification.


Course level: Advanced

This course is for engineers with good knowledge of "signal processing" and "radar". Knowledge of Fourier transforms and probability calculations basics will be taken for granted before the course begins.
