This concise one-day course is intended for those with only modest or no radar experience. It provides an overview with understanding of the physics behind radar, tools used in describing radar, the technology of radar at the subsystem level and concludes with a brief survey of recent accomplishments in various applications.

What You Will Learn:

  • What are radar systems, and how their intended applications control their spectrum and architecture
  • What are the key radar parameters and how they’re selected
  • What are the principal radar modes of operation
  • Radar waves propagation in space and the effects thereof of atmospheric refractivity and surface conditions
  • Radar wave scattering from targets and clutter
  • The radar range equation
  • Thermal noise and detection in thermal noise
  • Radar subsystems, including antenna, transmitter, receiver, and digital processors


Course Outline:

  1. Introduction: The general nature of radar: composition, block diagrams, photos, types and functions of radar, typical characteristics.
  2. The Physics of Radar: Electromagnetic waves and their vector representation. The spectrum bands used in radar. Radar waveforms. Scattering. Target and clutter behavior representations. Propagation: refractivity, attenuation, and the effects of the Earth surface.
  3. The Radar Range Equation: development from basic principles. The concepts of peak and average power, signal and noise bandwidth and the matched filter concept, antenna aperture and gain, system noise temperature, and signal detectability
  4. Thermal Noise and Detection in Thermal Noise: Formation of thermal noise in a receiver. System noise temperature (Ts) and noise figure (NF). The role of a low-noise amplifier (LNA). Signal and noise statistics. False alarm probability. Detection thresholds. Detection probability. Coherent and non-coherent multi-pulse integration.
  5. The Sub-Systems of Radar: Transmitter (pulse oscillator vs. MOPA, tube vs. solid state, bottled vs. distributed architecture), antenna (pattern, gain, sidelobes, bandwidth), receiver (homodyne vs. super heterodyne), signal processor (functions, front and back-end), and system controller/tracker. Types, issues, architectures, tradeoff considerations.
  6. Current accomplishments and concluding discussion.
