Title (EN) LADAR SYSTEM SUPPORTING DOUBLET WAVEFORM FOR SEQUENTIAL IN-PHASE (I) AND QUADRATURE (Q) PROCESSING
(FR) SYSTÈME LIDAR SUPPORTANT UNE FORME D'ONDE EN DOUBLET EN VUE D'UN TRAITEMENT SÉQUENTIEL EN PHASE (I) ET EN QUADRATURE (Q)
Abstract:
(EN) A method includes generating (702) a first optical signal (112) containing doublet pulses (302). Each doublet pulse includes a first pulse (304) and a second pulse (306). The second pulses of the doublet pulses are in quadrature with the first pulses of the doublet pulses. The method also includes transmitting (708) the first optical signal towards a target (102) and receiving (710) a second optical signal (116) containing reflected doublet pulses (402) from the target. Each reflected doublet pulse includes a first reflected pulse (404) and a second reflected pulse (406). The method further includes performing (714) in-phase and quadrature processing of the first and second reflected pulses and identifying (716) one or more parameters of the target based on the in-phase and quadrature processing.
(FR) L'invention concerne un procédé qui consiste à générer (702) un premier signal optique (112) contenant des impulsions en doublet (302). Chaque impulsion en doublet comprend une première impulsion (304) et une seconde impulsion (306). Les secondes impulsions des impulsions en doublet sont en quadrature avec les premières impulsions des impulsions en doublet. Le procédé comprend également la transmission (708) du premier signal optique vers une cible (102) et la réception (710) d'un second signal optique (116) contenant des impulsions en doublet réfléchies (402) à partir de la cible. Chaque impulsion en doublet réfléchie comprend une première impulsion réfléchie (404) et une seconde impulsion réfléchie (406). Le procédé consiste en outre à exécuter (714) un traitement en phase et en quadrature des première et seconde impulsions réfléchies et à identifier (716) un ou plusieurs paramètres de la cible en fonction du traitement en phase et en quadrature.
