The embodiment of the invention provides a helicopter self-adaptive forward-looking warning method and device and a helicopter, and belongs to the technical field of aircrafts. The method specificallycomprises the steps: obtaining a first data set, wherein the first data set comprises original terrain data and original obstacle data in a preset flight area of the helicopter; generating a forward-looking alarm area according to the current avionics data of the helicopter; acquiring real-time obstacle data corresponding to the forward-looking alarm area and detected by a radar of the helicopter; modulating a forward-looking alarm envelope of the helicopter according to the current avionics data of the helicopter; and performing collision detection on the real-time obstacle data and the first data set and the modulated forward-looking alarm envelope, and outputting an alarm result when a collision threat is detected. Obstacle data obtained by radar active detection is fused with terrainand obstacle data in an HTAWS system terrain database and an obstacle database in real time, so that the data confidence level is improved, and the forward-looking alarm detection capability is improved.

    本公开实施例提供一种直升机自适应前视告警方法、装置及直升机,属于飞行器技术领域。具体包括:获取第一数据集合,第一数据集合包括直升机的预设飞行区域内的原始地形数据和原始障碍物数据;根据直升机当前的航电数据,生成前视告警区域;获取直升机的雷达探测到的对应前视告警区域的实时障碍物数据;根据直升机当前的航电数据,调制直升机的前视告警包络;将实时障碍物数据和第一数据集合,与调制后的前视告警包络进行碰撞检测,并在检测到碰撞威胁时输出告警结果。将雷达主动探测得到的障碍物数据与HTAWS系统地形数据库、障碍物数据库中的地形、障碍物数据进行实时融合,提高数据置信等级,提升前视告警检测能力。
