Abstract: A receiving device comprises an analogue reception filter designed for a given frequency band included in the entire operating band of radar, the device further comprising a digital filter able to separate the received signals depending on their frequency, one portion of the frequency band of the given frequency band allocated to the radar reception function and another portion allocated to an RESM reception function.

Abstract: A transponder, able to equip a cooperative target facing a Doppler radar, includes at least one receiving antenna able to receive a signal transmitted by said radar and a transmitting antenna able to retransmit a signal. The signal received by the receiving antenna is amplitude-modulated before being retransmitted by the transmitting antenna to produce a variation of the radar cross-section of the target, the variation triggering a frequency shift between the signal transmitted and the signal received by the radar comparable to a Doppler echo. The transponder applies notably to the field of radars, more particularly for collaborative systems also operating at low velocity or nil velocity. It applies for example to assisted take-off, landing and deck-landing of drones, in particular rotary-wing drones, as well as manned helicopters.

Abstract translation: 能够装备面向多普勒雷达的协作目标的应答器包括能够接收由所述雷达发射的信号的至少一个接收天线和能够重发信号的发射天线。 接收天线接收到的信号在由发射天线重传之前进行幅度调制，以产生目标雷达横截面的变化，触发发射信号与雷达接收信号之间频移的变化可比 到多普勒回波。 应答器特别适用于雷达领域，特别适用于还以低速或零速度运行的协同系统。 例如，它适用于无人机，特别是旋翼无人机以及载人直升机的辅助起飞，着陆和甲板着陆。
