Claim 2:
3. The method of claim 1, wherein the target detection phase further comprises steps of:
scanning the lidar search signal over a plurality of additional search directions oriented with respect to the search direction, wherein, at the estimated range of the target, an angular field of illumination of the lidar search signal associated with each additional search direction overlaps at least partly with the angular field of illumination of the lidar search signal associated with the search direction;
receiving a corresponding plurality of additional search return signals produced by reflection of the lidar search signal from the target; and
refining, from the plurality of additional search return signals, the estimated angular location of the target; and
wherein, in the SA imaging phase, the imaging direction of the SA transmission signal is adjusted based on the refined estimated angular location of the target.
