Conclusions
Two different duplexers have been conceived, designed and tested that allow for using an Impulse UWB Radar in a monostatic configuration. The first one, which is based on a fast GaAs SPDT switch, is usable with a low peak power transmitter (<100 mW), while the second one, completely passive, is intended for high peak power applications (up to 50 kW). Both exhibit an instantaneous bandwidth covering the frequency range (400 MHz–4 GHz) which is the most suited frequency band for detecting burried antipersonel landmines by means of UWB radar. These duplexers contribute to a gain of space, weight and money, three important factors in the design of portable detection systems for humanitarian operations.
