LRDE
Electronics and Radar Development Establishment (LRDE) is a laboratory of the Defence Research & Development Organisation (DRDO), India. Located in C.V. Raman Nagar, Bengaluru, Karnataka, its primary function is research and development of radars and related technologies. It was founded by S. P. Chakravarti, the father of Electronics and Telecommunication engineering in India, who also founded DLRL and DRDL. LRDE is sometimes mis-abbreviated as "ERDE".

Airborne Surveillance Platform
The Airborne Surveillance Platform (ASP) is an Indian defence project initiated by the Defence Research and Development Organisation (DRDO) with the aim to produce an Airborne Early Warning System. Two prototypes were developed and flight tested for three years. The project was cancelled in 1999 after the prototype aircraft crashed, killing eight scientists and the aircrew. After four years of inactivity, the project was revived in 2004 with a new platform and radar. Origins The ASP programme, code-named "Airavat", is one of the key force multipliers in India's modern war scenario. DRDO is developing an advanced surveillance platform based on a Hawker Siddeley HS 748 aircraft to detect targets at extended ranges with all-around azimuth coverage. It is designed to handle 50 targets and features a hybrid navigation system, including both satellite and ground (beacon) based topography. The communication and data links are dual redundant secure systems. The origin of the programme p ... [...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 array antenna 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 matrix ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Defence Research And Development Organisation

DLRL
Defence Electronics Research Laboratory (DLRL) is a laboratory of the Defence Research & Development Organization (DRDO). Located in Hyderabad, it is actively involved in the design and development of integrated Electronic Warfare systems for the Indian Armed Forces. History DLRL was established in 1961 under DRDO, in order to meet the needs and requirements of electronic warfare systems for the Indian Armed Forces, including communication and radar systems. These functions were later handed over to specialized laboratories. Communication cipher equipment, developed by DLRL, was successfully deployed in the 1965 war with Pakistan. It was founded by S. P. Chakravarti, the father of Electronics and Telecommunication engineering in India, who also founded LRDE and DRDL. DLRL was included on the list of Indian entities that were subjected to US sanctions announced after the May 1998 nuclear tests.

Swordfish Long Range Tracking Radar
Swordfish is an Indian active electronically scanned array (AESA) long-range tracking radar specifically developed to counter ballistic missile threat. It will be a part of the Indian Ballistic Missile Defense Programme. First testing of this radar was in March 2009. Main aim of the test was to validate the capabilities of the ''Swordfish Long Range Tracking Radar'' (LRTR). "The missile to be hit will be fired from a longer distance than it was in the earlier test. DRDO tested whether the radar could track the incoming missile from that distance or not," said a member of the project. This radar is an acknowledged derivative of the Israeli EL/M-2080 Green Pine long range radar, which is the critical component of that country's Arrow missile defense system. However, it differs from the Israeli system as it employs Indian Transmit Receive modules, signal processing, computers and power supplies. It is also more powerful than the base Green Pine system and was developed to meet Ind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Battlefield Surveillance Radar
This is a list of different types of radar. Detection and search radars Search radars scan great volumes of space with pulses of short radio waves. They typically scan the volume two to four times a minute. The waves are usually less than a meter long. Ships and planes are metal, and reflect radio waves. The radar measures the distance to the reflector by measuring the time of the roundtrip from emission of a pulse to reception, dividing this by two, and then multiplying by the speed of light. To be accepted, the received pulse has to lie within a period of time called the ''range gate''. The radar determines the direction because the short radio waves behave like a search light when emitted from the reflector of the radar set's antenna. Search * Early Warning (EW) Radar Radar Systems ** Ground Control Intercept (GCI) Radar ** Airborne Early Warning (AEW) ** Airborne ground surveillance (AGS) ** Over-the-Horizon (OTH) Radar *Target Acquisition (TA, TAR) Radar Systems ** Surfac ...
