Abstract:
With the development of civic life details of humans and the enormous boom technological and architectural huge growing of population and increasing of the effects of global warming to touches the details of everyday reality, a new kind of problems which in the past were not significant or extreme gravity appeared. Wars and natural disasters steadily rising and left many trapped under the rubble of developing life who are unable to help themselves waiting for helping hand to stretch them.
Detecting survivors under the rubble became an urgent demand. Varied ideas and mechanisms were developed, in this research some of them have been discussed; representing, analyzing and comparison. The study concludes that the research and development in the human detection systems still need a lot of effort from researches institutions, studies centers and governmental agencies concerned with. The results of earlier efforts are still insufficient to achieve the required speed and efficiency. Connectivity of applications of this type of systems with the security and the lives of people directly, doubles the responsibility of who are able to help.
