Determination of cardinal direction

A device for detecting and/or tracking a projectile has a receiving antenna, for receiving at least an electromagnetic signal emitted by at least one radar, at least one amplifier configured to amplify the electromagnetic signal received by the receiving antenna, and at least one emitting antenna. The emitting antenna is configured to return, at an output of the device, an amplified electromagnetic signal for calculating data indicative of the trajectory of the projectile based at least on the amplified electromagnetic signal. A system for detecting a projectile has a transmitting device mounted on the projectile, a radar configured to sense an electromagnetic signal produced and sent by the transmitting device. The signals emitted from the projectile are limited to the electromagnetic signal sent by the transmitting device, and a processing unit, configured to calculate data indicative of the trajectory of the projectile, based on the sensing of the electromagnetic signal.

Methods and systems for detecting and/or tracking a projectile

A device for calibrating a radar or an antenna and embedded on an aerial vehicle, comprising: a processing unit configured to apply a delay to an incoming electromagnetic signal, wherein the device is configured to provide said electromagnetic signal with said delay to an emitter for its back transmission, wherein the processing unit is configured to control said delay according to one or more delay values, wherein each delay value simulates a virtual range of the device or of the aerial vehicle with respect to said radar or antenna receiving said transmitted electromagnetic signal, said virtual range being different from an actual range of the device or of the aerial vehicle, for calibrating said at least one radar or antenna based on said transmitted electromagnetic signal which simulates a virtual range of the device or of the aerial vehicle with respect to said at least one radar or antenna.
