This paper presents an electronic target designed for bistatic/monostatic synthetic aperture radar systems. The electronic target features two distinct antennas, so it can have different directions for transmitting and receiving. The electronic target basically receives a signal, down-converts it to baseband, applies a controllable time delay on the complex envelope, up-converts the delayed signal and transmits it towards the receiver of the bistatic/monostatic system. Since the delay is controllable, it can be used as artificial target with adjustable range. Even if the electronic target is placed in a cluttered area, its radar reflection can be moved away from its physical position.
