Methods and systems for detecting and/or tracking a projectile

A device configured to perform at least one of detecting and tracking a projectile, wherein the device is mounted on the projectile, wherein the device comprises:

• at least one receiving antenna mounted on the projectile, configured to receive at least an electromagnetic signal emitted by at least one active radar in the radio-frequency range,
• at least one amplifier mounted on the projectile configured to amplify the electromagnetic signal received by the receiving antenna, and
• at least one emitting antenna mounted on the projectile,
• wherein said emitting antenna is configured to return, at an output of the device, an amplified electromagnetic signal towards a radar or an antenna,
• wherein the amplified electromagnetic signal is usable for calculating data indicative of a trajectory of the projectile,
• wherein the amplified electromagnetic signal corresponds to the electromagnetic signal received by the receiving antenna mounted on the projectile or a signal informative thereof, after its amplification by said amplifier,
• wherein the device mounted on the projectile is configured to process the electromagnetic signal without down-converting a frequency of the electromagnetic signal by a down-converter,
• wherein the device is configured to maintain said electromagnetic signal in the radio-frequency range from its reception by the receiving antenna to its return as an amplified electromagnetic signal by said emitting antenna at the output of the device.
