Radar engineering details
Radar engineering details are technical details pertaining to the components of a radar and their ability to detect the return energy from moving scatterers — determining an object's position or obstruction in the environment.〔G. W. Stimson: "Introduction to Airborne Radar, 2nd Ed.," SciTech Publishing, 1998〕〔P. Lacomme, J.-P. Hardange, J.-C. Marchais, E. Normant: "Air and Spaceborne Radar Systems: An Introduction," IEE, 2001〕〔M. I. Skolnik: "Introduction to Radar Systems, 3rd Ed.," McGraw-Hill, 2005〕 This includes field of view in terms of solid angle and maximum unambiguous range and velocity, as well as angular, range and velocity resolution. Radar sensors are classified by application, architecture, radar mode, platform, and propagation window.
Applications of radar include Autonomous cruise control system, autonomous landing guidance, radar altimeter, air traffic management, early-warning radar, fire-control radar, forward warning collision sensing, ground penetrating radar, surveillance, and weather forecasting.
== Architecture choice ==
The angle of a target is detected by scanning the field of view with a highly directive beam. This is done electronically, with a phased array antenna, or mechanically by rotating a physical antenna. The emitter and the receiver can be in the same place, as with the monostatic radars, or be separated as in the
bistatic radars. Finally, the radar wave emitted can be continuous or pulsed. The choice of the architecture depends on the sensors to be used.
