surface wave radar
1Wave radar — Ocean surface waves can be measured by several radar remote sensing techniques. Several instruments based on a variety of different concepts and techniques are available to the user and these are all often called wave radars. This article (see… …
2Surface wave — Diving grebe creates surface waves In physics, a surface wave is a mechanical wave that propagates along the interface between differing media, usually two fluids with different densities. A surface wave can also be an electromagnetic wave guided …
3Continuous-wave radar — is a type of radar system where a known stable frequency continuous wave radio energy is transmitted and then received from any reflecting objects.[1]Continuous wave (CW) radar uses Doppler, which renders the radar immune to interference from… …
4Ocean surface wave — Ocean surface waves are surface waves that occur on the free surface of the ocean. They usually result from wind, and are also referred to as wind waves. Some waves can travel thousands of miles before reaching land. They range in size from small …
5Radar OTH — Radar trans horizon Un radar trans horizon, ou Over the horizon radar (OTH) est un équipement radar qui permet le repérage d une cible à très longue distance, de l ordre de quelques milliers de kilomètres. Sommaire 1 Principe de fonctionnement 2… …
6Radar — For other uses, see Radar (disambiguation). A long range radar antenna, known as ALTAIR, used to detect and track space objects in conjunction with ABM testing at the Ronald Reagan Test Site on Kwajalein Atoll …
7Radar altimeter — A radar altimeter, radio altimeter, low range radio altimeter (LRRA) or simply RA measures altitude above the terrain presently beneath an aircraft or spacecraft. This type of altimeter provides the distance between the plane and the ground… …
8Radar trans-horizon — Un radar trans horizon, ou Over the horizon radar (OTH) est un équipement radar qui permet le repérage d une cible à très longue distance, de l ordre de quelques milliers de kilomètres. Sommaire 1 Principe de fonctionnement 2 Historique 2.1… …
9Radar de mesure balistique — Un radar de mesure balistique est un radar utilisé pour mesurer, grâce à l effet Doppler Fizeau, certaines caractéristiques du mouvement d un projectile sur un segment de sa trajectoire situé ou non hors d un canon. Description Le type et la… …
10Radar warning receiver — Typically fitted to military aircraft, radar warning receivers (RWR) detect the radio emissions of radar systems, whether ground based or on board other aircraft. The system is often capable of classifying the source of the radar by type (Pulsed… …
