The preceding chapters have devoted some detail to the fundamental aspects of radar: transmission/reception; antennas; waveforms; propagation; RCS; SNR; detection; and accuracy of measurement of range, velocity, and angular position. This chapter combines those fundamentals and considers the particular advantage of applying those techniques to the case of a rotating target, which leads us to the important domain of imaging radar.

Chapter Contents:

  • 6.1 Range-Velocity Compression
  • 6.2 Rotating Target; Inverse Synthetic Aperture Radar
  • 6.3 ISAR for an Extended Target
  • 6.4 Point-Spread Function
  • 6.5 Standard Two-Dimensional ISAR: Small Angles
  • 6.6 Two-Dimensional ISAR: Large Angles
