Radar Systems

Radar Systems | General Awareness for SSC CGL

India has developed several advanced radar systems, primarily through the Defence Research and Development Organisation (DRDO). These radars serve various roles, from air defense to artillery tracking and naval applications. Below is an overview of some key radar systems:

Rajendra Radar

Radar Systems | General Awareness for SSC CGL

Developed by DRDO, the Rajendra Radar is a multifunctional radar system integral to the Akash Surface-to-Air Missile (SAM) system. It is capable of performing surveillance, tracking, and engaging targets with low radar cross-section. Notably, its multi-element antenna setup can be folded flat when the vehicle is in transit.

Indian Doppler Radar (INDRA)

Radar Systems | General Awareness for SSC CGL

The INDRA series consists of 2D radar systems developed by DRDO for different applications:

  • Indra I: A 2D mobile surveillance radar designed for low-level target detection. It is mounted on two wheeled vehicles for mobility.
  • Indra II: A variant of the Indra series, this radar is tailored for ground-controlled interception of targets.

Swordfish Radar

The Swordfish Radar is a long-range tracking radar designed by India to counter ballistic missile threats. It is a derivative of the Israeli Green Pine radar, adapted to meet specific Indian defense requirements.

Swathi WLR

The Swathi Weapon Locating Radar (WLR) is a mobile, phased array radar system developed by India. It is designed for counter-battery operations, detecting and tracking incoming artillery and rocket fire, and accurately determining their points of origin for counterattacks.

Aparna

Aparna is a naval radar system that can detect enemy ships and provide early warnings for self-defense. It has already been commissioned into service with the Indian Navy.

Rohini Radar

The Rohini is a 3D radar system developed by DRDO for integration with the Akash SAM system, capable of tracking up to 150 targets simultaneously. The Indian Air Force operates the Rohini, while its naval variant, known as Revathi, is used by the Indian Navy.

AWACS (Airborne Warning and Control System)

AWACS, also referred to as the NETRA Airborne Early Warning and Control System, is an airborne radar platform designed to detect aircraft, ships, and vehicles over long ranges. It plays a critical role in providing early warning and control capabilities.

FAQs on Radar Systems - General Awareness for SSC CGL

1. What are some examples of radar systems used in India?
Ans. Some examples of radar systems used in India include Rajendra Radar, Indian Doppler Radar (INDRA), Swordfish Radar, Swathi WLR, Aparna, Rohini Radar, and AWACS (Airborne Warning and Control System).
2. What is the purpose of a radar system?
Ans. The purpose of a radar system is to detect and track objects such as aircraft, ships, spacecraft, vehicles, and weather formations by transmitting electromagnetic waves and analyzing the echoes reflected back.
3. What is the significance of Doppler radar in radar systems?
Ans. Doppler radar is significant in radar systems as it allows for the measurement of the velocity of objects by detecting changes in frequency caused by motion. This information is crucial for applications like weather forecasting and air traffic control.
4. How does the Swathi WLR radar system differ from other radar systems?
Ans. The Swathi WLR radar system is a weapon locating radar used by the Indian Army to precisely detect and track enemy artillery and rocket positions. It is specifically designed for battlefield surveillance and target acquisition.
5. How does the AWACS radar system enhance air defense capabilities?
Ans. The AWACS (Airborne Warning and Control System) radar system enhances air defense capabilities by providing early warning of incoming aircraft or missiles, as well as monitoring and coordinating air traffic. This allows for better situational awareness and response to potential threats.
