Problem

Radio waves doesn't work in electronically jammed environment.

Problem Formulation

1. Find alternative to radio waves to sense target.

2. Find other properties of target. Does target vibrates, makes sounds or does it has some other footprints.

3. The data transfer from field to command center can not be radio based. There has to be cables or something. which can not be electronically jammed.

Approach

1. Focus on meta data of the target.

2. Focus on the data transfer mechanism.

3. The solution shall be enough competent as that of radio based solutions.

4. The solution shall be cheap, practical and mass produced.

Technology used

Come up with scalable, cheap, sturdy and easily deployable software and hardware solutions at paar to available radar solutions

Hardware used

RaspberryPI

Cardioid Parabolic microphones

Vibration sensors

Fiber optic

Architecture

Achievement at London Hackathon

We used three UGVs mounted with our prototype cube with onboard microphones. For communication, fiber optic or ethernet cables are used. The UGVs are deployed in the environment. Cubes collect sounds and push it into the network. 

The data in the network can be accessed by any computer. The software is written in such as way that you can add as many as hundreads of Cubes to generate sound fence or vibration fence.

Next steps

Build an intelligence to extract drone sounds, enemy footsteps, moving tanks or all kinds of sound and vibration patterns from collected Cubes.
