Abstract:
1. A radar processor for controlling detonation of a munition and operable to receive a detonation altitude from an external source, the radar processor configured to: set a first range gate and a reference range gate based on the received detonation altitude; cause a radar transmitter to operate in a continuous wave mode, for a predetermined period, upon receipt of radar return signals through the first range gate; calculate a velocity of the munition from continuous wave return signals; calculate a time delay for outputting a detonation signal based on the received detonation altitude, the calculated velocity, and a reference altitude of the munition, the altitude of the munition calculated based upon receipt of radar return signals through the reference range gate; and wherein the radar processor is configured to cause the radar transmitter to operate in a pulse mode while the munition is outside the reference range gate.
