Abstract:
1. A method for imaging objects located within a predetermined range from a sensor having multiple individual energy wave detectors disposed in a predetermined array, said method comprising the steps of: (a) transmitting a pulse Of said energy in the general direction of said objects; (b) in time synchronization with transmission of said energy pulse in step (a), initiating a global time-varying measurement signal having a predetermined duration and a specified parameter with a value that both varies with time and is non-repetitive throughout said predetermined duration; (c) receiving respective reflections of said energy pulse from said objects at detectors in said array; (d) at each detector, storing the value of said global measurement signal parameter at the time of reception of said reflection in step (c); and (e) representing said objects as a function of the parameter values stored at said detectors.
