Abstract : A frequency agile optical radar system including a frequency agile laser source coupled with an extra-cavity dispersive element in such a manner as to radiate into space specific optical frequencies correlated with specific elevation angles measured from the horizontal. Laser radiation reflected from an object in space is detected by a staring detector system and the wavelength of the reflected optical energy determined therefrom. the elevation angle of the object in space is correlated with the optical frequency determination and coupled together with target range and aximuth angle so that the position and range to an object in space may be determined.
