Coherent also means expressing yourself clearly: I should warn you, she’s not always coherent. coherently adverb us / koʊˈhɪər·ənt·li / WebA measurement of the accurate azimuth of the target is still defined herein in the center of the blip on the screen. (The distance is measured at the front edge of this blip.) Many radares use pulse integration in the radar signal processing to distinguish the target signals from noise and interference pulses.

WebCoherent radar target detection against heavy-tailed non-Gaussian clutter is the subject of the third part of the course. In high resolution radar systems the disturbance cannot be modelled as Gaussian distributed and the classical detectors suffer from high losses.

Only within the coherence length, interference is possible. In fully …
