Reduced-Dimension FDA-STAP for Range-Ambiguous Clutter Rejection Under Limited Snapshots

Eng
Space-time adaptive processing (STAP) has been widely recognized as an effective technique for suppressing clutter in airborne radar systems. Nevertheless, range ambiguity can seriously affect the clutter rejection capability of conventional STAP methods.

Ewing Sarcoma in Infants and Children Under 2 Years of Age: A French Retrospective Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Ewing sarcoma, the second most common primary bone cancer in children, requires intensive treatment that may lead to significant long‐term sequelae, particularly in infants. We retrospectively analyzed data from 1621 French patients treated between 1988 and 2015 within the EW88/93/97 or EE99 trials, focusing on 17 infants diagnosed before 24 ...

Joint design of transmit beamspace and reduced‐dimension receiver filter for MIMO radar STAP

IET Radar, Sonar & Navigation, 2021
In this article, the problem of the transmit beamspace (TB) matrix design in multiple‐input multiple‐output (MIMO) radar is considered. To reduce the computational burden and to focus the energy within optimal spatial sector, a joint design method of the
