METHOD AND APPARATUS FOR DETECTING A TERRAIN-MASKED HELICOPTER |
| 摘要 |
A robot sentry (40) with a scanning laser (45) observes the sky just above the geographic skyline (20) looking for a vertical airflow pattern characteristic of the rotor inflow to a helicopter rotor. The presence of this vertical airflow pattern indicates the probable presence of a reconnaissance helicopter (10) that is using terrain masking. |
