Walls Penetrating surveillance system

Walls penetrating surveillance system is about tracking and locking of target hiding out inside homes and it is all about modern urban warfare system.

I have worked on this system as my final year thesis and i got suceeded in it , a thing of joy for me and for my university .


        When we talk about wall penetrating surveillance we talk about the hurdles between us and the target and all thats matter.

A common question arises among students and teachers that what ray can pass through the walls and what if it pass through the target. It is common belief that the ray pass through the wall will also pass through the target, my answer to this is a big NO. i see at this in quite different way , my beliefs are differents i want to tell you thast whenever the waves passes through on e to other medium a sudden disrupt change occurs in there properties and whole story is based on this simple sentence.

       Now the question is that how wall pentrating surveillance system works . Actually when we send or transmit waves in a medium it travels depending upon the properties of medium and also when it face toward the other medium there properties canges at the point of interface between the two mediums how it change suddenly or gradually that depends upon nature of medium and all this occurs because of the permitivity of mediums and also the permeability of mediums are differents which affects the properties of waves which are almost electromagnetic one .

Now look if we send the waves with some definite properties towards walls than at the interface of the walls we have change of medium and that is the point where some reflection of waves occurs  , a part of wave penetrate in the wall and remaining part reflects back and how it happens because of permitivity and  permeability which also relates to snells law and  also to transmission and reflection coefficients and also upon polariztion of fields and there different modes  .

The transmitted part again go through the same transmission and reflection at second interface of wall and also when incident upon target it agains transmitted and some part reflected .
when we analyse the all reflections at our receving devices we pooin that which is target and which is wall reflection .


Anyone can see it also on my personal website
