Antenna system
First Claim
1. A method for scheduling radar transmissions for a phased array antenna system having at least two antenna faces, each respective antenna face of the at least two antenna faces configured to receive echoes of possible targets corresponding to previous radar transmissions by said each respective antenna face, and said method comprising:
- determining, based on a list of requested radar transmissions, a scheduling process including starting times of radar transmissions for each of the at least two antenna faces for substantially each radar transmission included in the list of requested radar transmissions, wherein the scheduling process is arranged such that the at least two antenna faces are used substantially simultaneously, transmission by a first antenna face of the at least two antenna faces is prevented when a second antenna face of the at least two antenna faces is about to receive echoes corresponding to possible targets, and trailing edges of first and second radar transmissions for each of the at least two antenna faces are aligned so the first and second radar transmissions end at substantially the same time even when the first and second radar transmissions begin at different times, and wherein radar transmissions for the at least two antenna faces are substantially mutually synchronized.

Abstract
A method for scheduling radar transmissions for a phased array antenna system having at least two antenna faces, in which each respective antenna face is configured to receive echoes of possible targets corresponding to previous radar transmissions by the respective antenna face. The method includes determining, based on a list of requested radar transmissions, a scheduling process including starting times of radar transmissions for each of the antenna faces for substantially each radar transmission included in the list of requested radar transmissions. Further, the scheduling process is arranged such that the antenna faces are used substantially simultaneously, transmission by an antenna face is prevented when another antenna face is about to receive echoes corresponding to possible targets, and radar transmissions for each antenna face end at substantially the same time. In addition, radar transmissions for the antenna faces are substantially mutually synchronized.
