L&T has developed the following radars for ground and sub-surface applications:-

Ground Penetrating Radars

L&T has designed and developed a state-of-the-art ground penetrating radar. This system is extremely compact and can be engineered to fit either ahead of vehicles/tanks or can be towed. The system can detect metal and non-metal objects up to a depth of 4M in all types of soil conditions and snow. The system utilises high-end algorithms enabling the user to see the image of the object and also provide 3D positioning of the object.

Dual Technology Mine Detector

DTMD (Dual Technology Mine Detector) is a hand-held sensor system combining a conventional metal detector of high sensitivity and a Ground Penetrating Radar (GPR) for detection of buried landmines. The equipment has been specially developed by Larsen & Toubro for military applications as well as for humanitarian de-mining operations. The conventional metal detector provides audio alarms on presence of metallic objects. The Ground Penetrating Radar (GPR) has been integrated with the metal detector for detection of non-metallic mines which are increasingly being deployed currently to avoid detection. The equipment is designed to provide audio and video indications on presence of both metallic and non-metallic mines in different types of soil with very low probability of false alarms.
