METODO ED APPARECCHIATURA PER L'ESTRAZIONE DI UNA MAPPA DEGLI OSTACOLI DAL SEGNALE DI UN RADAR VEICOLARE A SCANSIONE CON TRASMISSIONE IMPULSIVA

In order to extract a map of obstacles from the signal of a scanning pulsed-transmission radar detector, for vehicles, use is made of a method and an apparatus which include: the analogue processing of the mid-frequency radar echo signal, which consists in a wide-band amplification, with automatic control of the gain of the "variable- over-time gain" type, followed by a pulse-matched bandpass filtering; video detection; digital processing of the video signal, which consists in generating a binary map of the detections of a radar scan by means of a "moving window" integration of sequences of single-bit quantised samples of the radar echo; storage of the said map; and formulation of the list of obstacles, which consists in plotting the beam-aiming data and in applying a "plot extraction" procedure to the map of detections thereby obtaining the data indicative of position in range and in azimuth and of transverse extent of the objects detected by the radar detector.
