Space-delay adaptive processing for MIMO RF indoor motion mapping

Conference Paper

In this paper, space-delay adaptive processing (SDAP) is proposed for motion mapping using MIMO RF signals. Typically, indoor RF localization methods require ultra-wideband signals to achieve the time-delay resolution required for separation of returns in complex multipath environments. Due to spectrum use restrictions, however, there is a need for methods which can operate using the lower bandwidths allocated for so-called ISM use. In this paper, we develop SDAP methods for linear MIMO transmit-receive arrays which can achieve near ultra-wideband range resolution and multipath sidelobe suppression but which use significantly less bandwidth. Real data results for indoor motion monitoring are presented aimed at mapping patient repositioning activities in long-term care facilities for pressure ulcer prevention.
