This chapter investigates techniques for measuring the angular location of a target by the use of multiple subapertures and by comparing the signals received from them, and examined the potential accuracy of target angle measurement using a single-aperture radar.

Chapter Contents:

  • 5.1 History and Terminology
  • 5.2 Monopulse
  • 5.2.1 Monopulse: A General Case
  • 5.2.2 Monopulse with Uniform-Odd Illumination on Difference Aperture
  • 5.3 Interferometric Radar
  • 5.3.1 Case 1: Zero Spacing Between Subaperture Edges (w = 2S)
  • 5.3.2 Case 2: Nonzero Spacing, Constant Subaperture Width (w = 2S)
  • 5.3.3 Case 3: Nonzero Spacing, Constant Overall Aperture Width
  • 5.4 Glint
