space-time adaptive processing (STAP)

详 情 说 明

Space-Time Adaptive Processing (STAP) is a signal processing technique used in radar systems to detect and track moving objects in cluttered environments. It is used to filter out unwanted signals from radar returns, allowing for improved detection of targets of interest. STAP works by analyzing the spatial and temporal properties of the radar signal, and adapting the processing parameters in real-time to optimize the signal-to-noise ratio. This technique is particularly useful in situations where there are many interfering signals, such as in airborne or ground-based radar systems. STAP has been successfully applied in a range of fields, including meteorology, geology, and defense.
