Title:
展開可能な送信／受信モジュール装置を有するラムジェット付き無人航空ビークル
Document Type and Number:
Japanese Patent JP6862273
Kind Code:
B2
Abstract:
A system for bistatic radar target detection employs an unmanned aerial vehicle (UAV) (14) having a ramjet engine (30) providing supersonic cruise of the UAV (14). Deployable antenna arms (22) support a passive radar receiver for bistatic reception of reflected radar pulses. The UAV (14) operates with a UAV flight profile in airspace beyond a radar range limit. The deployable antenna arms (22) have a first retracted position for supersonic cruise and are adapted for deployment to a second extended position acting as an airbrake and providing boresight alignment of the radar receiver. A mothership aircraft (10) has a radar transmitter for transmitting radar pulses and operates with an aircraft flight profile outside the radar range limit. A communications data link operably interconnects the UAV (14) and the tactical mothership aircraft (10), transmitting data produced by the bistatic reception of reflected radar pulses in the UAV radar antenna (46) to the mothership aircraft (10).
