- The Archaeological Survey of India (ASI) and Indian Institute of Technology-Madras (IIT-M) will carry out mapping of the Bagh-e-Naya Qila inside the Golconda Fort using Ground Penetrating Radar (GPR) technology.
- The Naya Qila garden inside Golconda Fort was built during the Qutb Shahi rule (1518-1687).
- The Naya Qila area also has multiple chabootras (raised platforms) which are remains of garden structures that pre-date the Qutb Shahi rule.
- An earlier excavation unearthed gold coins in the area where the golf course has been created.
- Further in 2014, the ASI discovered water channels, settlement tanks, walkways, fountains, gravity pumps, and a host of other garden relics.
- It should be noted that Hyderabad Gold Club wants to expand its 18-hole course into a 21-hole one by taking over some of the land adjoining the Bagh-e-Naya Qila site.
Ground penetrating radar technology
- GPR uses electromagnetic radiation in the microwave frequency for imaging sub-surface area.
- High frequency radio signal in microwave frequency is transmitted into the ground.
- The material underground reflects these signals which are captured by the receiver.
- By measuring the time taken for the signal to travel to and from the target, the depth and location of the material can be calculated.
- Ground-penetrating radar (GPR) works around 500 MHz frequencies to detect archaeological structures.
