Radar is a system that uses radio waves to determine the distance (), direction (azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method [1] used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain.
Radio-frequency (RF) engineering is a subset of electrical engineering involving the application of transmission line, waveguide, antenna, radar, and electromagnetic field principles to the design and application of devices that produce or use signals within the radio band, the frequency range of about 20 kHz up to 300 GHz.
Most are familiar with the military uses of the technology on Laser-guided bomb. The space shuttle crew leverages a hand held device to feed information into rendezvous planning. The primary limitation on this device is that it requires a line of sight between the target and the designator. Terrain contour matching . Uses a ground scanning ...
The Radar Course Directing Central was an outgrowth of the July 1945 Signal Corps' Project 414A's [11] planned Fire Direction Center System and a 1950 prototype computer and console system. [12] Contractor evaluation of the first fire control system for Nike was from January–May 1953, and the "prototype model battery" system for the Nike Ajax ...
Space-time adaptive processing (STAP) is a signal processing technique most commonly used in radar systems. It involves adaptive array processing algorithms to aid in target detection. Radar signal processing benefits from STAP in areas where interference is a problem (i.e. ground clutter, jamming, etc.). Through careful application of STAP, it ...
Radar engineering is the design of technical aspects 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.
Further examination of the basic Radar Spectrum shown above shows that the information in the various lobes of the Coarse Spectrum is identical to that contained in the main lobe, so limiting the transmit and receive bandwidth to that extent provides significant benefits in terms of efficiency and noise reduction.
Mark Andrew Richards (January 20, 1952) is a retired American engineer best known for his textbooks and professional education courses in the area of radar and radar signal processing. He remains employed part time as a Principal Research Engineer and adjunct professor in the School of Electrical and Computer Engineering (ECE) at the Georgia ...
