Empirical study of stepped-FM UWB microwave sensor
This paper presents an ultra wideband (UWB) microwave sensor using a stepped-FM scheme. Impulse-radio UWB sensor requires high speed A/D in order to synchronize and detect the nanosecond pulse echo. Also it may be difficult to use the bandwidth wider than 500MHz without causing interference with other wireless systems. Our suggested scheme which does not require any high speed A/D devices can coexist with other wireless systems since spectrum holes (non-activated within a portion of the radio spectrum) are easy to be designed over specific bandwidth. In this paper, the measurements were conducted using the experimental device and the above mentioned characteristic is investigated.
