TRML
The TRML ( or "Telefunken mobile airspace surveillance radar") is a family of air defense radars first developed by Telefunken and currently produced by Hensoldt. It is a development of the earlier TRMS ( or "Telefunken mobile search radar"). Retractable mast versions are TRML-2D with a rotating parabolic antenna and TRML-3D with a rotating phased array antenna, designated as ''Nahbereichsradar'' (NBR) or "short range radar" by the Bundeswehr. The latest TRML-4D comes with non-retractable, rotating base active electronically scanned array (AESA) solid-state antenna. System description TRML-2D was designed as an autonomous mobile command system for air defense with an integrated search radar. It can detect, identify and track aircraft at low and medium altitude, designate targets for the connected launchers and send commands to the battle management network. The range of the radar is 60 km for TRML-2D, 200 km for the TRML-3D/32, and 250 km for TRML-4D. The c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IRIS-T SLM Radar Unit TRML-4D ILA-2022
The IRIS-T (infrared imaging system tail/thrust vector-controlled) is a family of short range infrared homing air-to-air and short to medium range surface-to-air missiles. It is also called AIM-2000. The missile was developed in the late 1990s–early 2000s by a German-led program to produce a short to medium range infrared homing air-to-air missile to replace the AIM-9 Sidewinder in use by some NATO member countries at the time. A goal of the program was for any aircraft capable of firing the Sidewinder to also be capable of launching the IRIS-T. The air-to-air variant was fielded in 2005. Surface-to-air defence systems variants came later, with the short-range IRIS-T SLS fielded in 2015, and the medium-range IRIS-T SLM fielded in 2022. One IRIS-T SLM battery, as supplied by Germany to Ukraine, consists of three truck-mounted launchers, carrying eight missiles each (with a range of ), and a separate command vehicle that can be positioned up to away. The command vehicle inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Active Electronically Scanned Array
An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled antenna array in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna. In the AESA, each antenna element is connected to a small solid-state transmit/receive module (TRM) under the control of a computer, which performs the functions of a transmitter and/or receiver for the antenna. This contrasts with a passive electronically scanned array (PESA), in which all the antenna elements are connected to a single transmitter and/or receiver through phase shifters under the control of the computer. AESA's main use is in radar, and these are known as active phased-array radar (APAR). The AESA is a more advanced, sophisticated, second-generation of the original PESA phased-array technology. PESAs can only emit a single beam of radio waves at a single frequency at a time. The PESA must utilize a Butler matri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. The largest use of phased arrays is in radars. Most phased array radars in the world are PESA. The civilian microwave landing system uses PESA transmit-only arrays. A PESA contrasts with an active electronically scanned array (AESA) antenna, which has a separate transmitter and/or receiver unit for each antenna element, all controlled by a computer; AESA is a more advanced, sophisticated versatile second-generation version of the original PESA phased array technology. Hybrids of the two can also be found, consisting of subarrays that individually resemble PESAs, where each subarray has its own RF front e ...

ISO Container
An intermodal container, often called a shipping container, or a freight container, (or simply "container") is a large metal crate designed and built for intermodal freight transport, meaning these containers can be used across different modes of transport – such as from ships to trains to trucks – without unloading and reloading their cargo. Intermodal containers are primarily used to store and transport materials and products efficiently and securely in the global containerized intermodal freight transport system, but smaller numbers are in regional use as well. It is like a boxcar that does not have wheels. Based on size alone, up to 95% of intermodal containers comply with ISO standards, and can officially be called ISO containers. These containers are known by many names: cargo container, sea container, ocean container, container van or sea van, sea can or C can, or MILVAN, or SEAVAN. The term CONEX (Box) is a technically incorrect carry-over usage of the name of an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
