Millimeter wave radars are employed in a wide range of commercial, military and scientific applications for remote sensing, safety, and measurements. Millimeter wave sensors are superior to microwave and infrared-based sensors in most applications. Millimeter wave radars offer better range resolution than lower frequency microwave radars, and can penetrate fog, smoke and other obscurants much better than infrared sensors. Some of the most commonly employed millimeter wave radar subsystems are:
  • Automobile Collision Warning sensor
  • Autonomous Cruise Control
  • Robotic vision
  • Surveillance - Air Defense, Sniper/Artillery location-tracking
  • Altimeters and Height/depth measurement
  • Missile guidance and tracking
  • Speed and range measurement for industrial uses
  • Industrial depth measurement in hostile environment
  • Severe weather studies and measurement
  • Clear Air Turbulence/Wind Field measurements
  • Wide area traffic monitoring and control
  • Intrusion detection
  • Aircraft collision warning/obstacle detection system for helicopters, Unmanned Aerial Vehicle (UAV), Unmanned Surface Vehicle (USV)
  • Harbor monitoring/Navigation guidance
  • Imaging
  • Vision/sensing in adverse weather/environment
  • Presence/motion Sensors for automated systems
  • Safety and security devices

Millimeter wave radars are generally classified in two broad categories with several specific variations or modes of operation associated with each type:

Pulsed Radars:

  • Coherent Pulsed
  • Doppler/Moving Target Indicator
  • Incoherent Pulsed
  • Pulse Compression (FM/PM/Polarization diversity)

CW radars:

  • Doppler
  • Freq. Modulated (FMCW)
  • Phase Modulated and Multi-frequency waveform

In each case, the radar determines the size, characteristics, range and velocity of the object or scene by measuring the characteristics of the return signal after reflection/scattering from it. The amplitude, spectral contents and the time of arrival of the return signal yields the necessary information regarding the observed scene or object.
