A device for providing an altitude estimate Best in a missile, comprises
- a radar seeker (3) comprising a radar antenna (4) for measuring a distance r to a point as a distance range comprising at least two range bins (9)
- a calculating unit (11) for providing a component altitude estimate a est (s) for each of the at least two range bins, as a function of r and ¸, r being the distance to the respective range bin (9) and ¸ being the elevation angle,
- said calculating unit also being arranged to provide the altitude estimate a est based on the at least two component altitude estimates a est (s). Thus an altitude estimate may be provided in a military tactical missile that does not have an altimeter. |
