Abstract: A method and fire control system for measuring distance to a burst point of airburst munition including: setting a detonation point distance of airburst munition; firing the weapon with airburst munition at time t0; setting a time of flight, t1, of the airburst munitions based on its set detonation point distance, activating and controlling a laser measurement system including a laser transmitter and receiver for sending laser light at a time t0+t1 and receiving reflected laser light for measuring distance to cloud of smoke resulting from burst of the airburst munition, processing the reflected laser light and defining a range of distances to the cloud of smoke, and setting a range gate around the set detonation point distance prior to processing received reflected laser light within the range gate for limiting the resulting range of distances and cancelling echoes from surrounding terrain.
