1.4 Support of the Thesis 4 a contribution of this thesis and possible extensions of the research are proposed in Section 5. 1.4 Support of the Thesis This thesis originated within the support of the project Ultra Wideband Radio application for localisation of hidden people and detection of unauthorised objects (Acronym: RADIOTECT) co-funded by the European Commission within the Sixth Framework Programme under the contract COOP-CT-2006-032744 [38], project Digital Processing of UWB Radar Signals (Acronym: DSP-UWB-RAD), and the Slovak Research and Development Agency under the contract No. LPP- 0287-06.
Chapter 2 State Of The Art 2.1 UWB Radar Systems 2.1.1 History of Radar Christian Huelsmeyer gave public demonstrations of the use of radio echoes to detect ships so that collisions could be avoided in Germany and the Netherlands in 1904. System consisted of a simple spark gap aimed using a multipole antenna. When a reflection was picked up by the two straight antennas attached to the separate receiver, a bell sounded. The system detected the presence of ships up to 3 km. It did not provide range information, only warning of a nearby metal object, and would be periodically ”spun” to check for ships in bad weather. He patented the device, called the telemobiloscope, but due to lack of interest by the naval authorities the invention was not given into production [16]. Nikola Tesla proposed principles regarding frequency and power levels for primitive radar units in August 1917. Tesla proposed the use of standing electromagnetic waves along with pulsed reflected surface waves to determine the relative position, speed, and course of a moving object and other modern concepts of radar [94]. The World War II moved forward developing of airborne radars [22]. The next major development in the history of radars was the invention of the cavity magnetron by John Randall and Harry Boot of Birmingham University in early 1940’s. This was a small device which generated microwave frequencies much more efficiently. The UWB term was at first used in the late 1960’s Harmuth at Catholic University of America, Ross and Robbins at Sperry Rand Corporation and Paul van Etten at the USAF’s Rome Air Development Center [13]. Till the end of 20th century there were lot of radar types for different applications like airborne radars, ground penetrating radars, sonars, and one which will be discussed further in detail the through-wall penetrating radar. 5
