High resolution time of arrival estimation for a cooperative sensor system [PDF]

Advances in Radio Science, 2010
Distance resolution of cooperative sensors is limited by the signal bandwidth. For the transmission mainly lower frequency bands are used which are more narrowband than classical radar frequencies. To compensate this resolution problem the combination of
