Abstract
An arrangement for controlling radar transmissions for a system of antennas disposed on a moving platform. The radar transmissions are allocated to an antenna face for a future transmission. To effect an adequate allocation, a prediction arrangement is provided to predict the angular position of the moving platform and the antenna faces. Preferably an antenna is assigned that realizes the smallest off-broadside angle of the radar transmission.
Claims24
A radar system for performing radar transmissions, comprising:
- at least a first antenna and a second antenna with different broadside directions and disposed on a moving platform;
- an angle predictor configured to predict an angular position of a coordinate system connected to the moving platform with respect to a reference coordinate system;
- and
- an antenna selector, connected to the angle predictor and configured to allocate a radar transmission requested for transmission within a future time window to one of the at least first antenna and second antenna.
A method for allocating a radar transmission, requested for transmission within a future time window, to one antenna of a system containing at least first and second antennas with mutually different broadside directions, and disposed on a moving platform, comprising the steps of:
- predicting an angular position of a coordinate system connected to the platform with respect to a reference coordinate system;
- and
- allocating a radar transmission to an antenna if, within the future time window and throughout the longest time span, a transmit direction of the radar transmission realizes the smallest predicted off-broadside angle with this antenna.
