| 1 | It works by shining a hollow laser beam around small glass particles, as Inside Science explains. | |
| 2 | Directional antennae, unlike the omnidirectional sort, transmit on a narrow beam. | |
| 3 | DOA information can be used in initializing the weights of the adaptive beamforming. | |
| 4 | The missile "rides" the beam; that is , it follows the radar signal until it hits the target. | |
| 5 | During that test, an onboard calorimeter captured the laser beam before it left the aircraft. |
