Difference between Radar and Sukhoi Su-27

Radar vs. Sukhoi Su-27

Radar is a system that uses radio waves to determine the distance (ranging), direction (azimuth and elevation angles), and radial velocity of objects relative to the site. The Sukhoi Su-27 (Сухой Су-27; NATO reporting name: Flanker) is a Soviet-origin twin-engine supersonic supermaneuverable fighter aircraft designed by Sukhoi.

Electronic countermeasure

An electronic countermeasure (ECM) is an electrical or electronic device designed to trick or deceive radar, sonar, or other detection systems, like infrared (IR) or lasers.

Look-down/shoot-down

A radar system has look-down/shoot-down capability if it can detect, track and guide a weapon to an air target that (as seen by the radar) is silhouetted against the ground.

Passive electronically scanned array

A passive electronically scanned array (PESA), also known as passive phased array, is an antenna in which the beam of radio waves can be electronically steered to point in different directions (that is, a phased array antenna), in which all the antenna elements are connected to a single transmitter (such as a magnetron, a klystron or a travelling wave tube) and/or receiver.

Pulse-Doppler radar

A pulse-Doppler radar is a radar system that determines the range to a target using pulse-timing techniques, and uses the Doppler effect of the returned signal to determine the target object's velocity.

Radar cross section

Radar cross-section (RCS), denoted σ, also called radar signature, is a measure of how detectable an object is by radar.

Synthetic-aperture radar

Synthetic-aperture radar (SAR) is a form of radar that is used to create two-dimensional images or three-dimensional reconstructions of objects, such as landscapes.
