sorry for the delay in reply.......
i feel that with this kinda support that this forum extends, i will be able to do the project successfully. thanks for techraptor and docel........
all the technologies mentioned by techraptor seems to be too techi and at the level of ug, i feel it is not the tme to get that deep into the issue.
but i would be graetful if techraptor helps me out with links and resources for the GPR method.
and sir(DOCEL) u mentioned about "someone" working on the similar field at some place..... can u please reffer me to the link, so that i can take a look at the work.... or can u give me the address so that i can take a look physically and mentally......
down thw lane i did some search for the tech matter in the detection of landmines using IR images...... the thermal difference caused by the explosive give differential thermal picture and not the heating nature of the metal..... pardon me for my ignorance
