Non-uniform multi-beam satellite communications system and method

A spacecraft broadcast method, comprising:

• broadcasting multiple communication signal beams from a spacecraft to different respective target area locations so that at least some of said beams have different sizes at their respective target locations, and
• providing different respective signal frequency spectrums for at least some of said beams.

A spacecraft broadcast method, comprising:

• broadcasting multiple communication signal beams from a spacecraft to different respective target area locations with at least some of said beams having different beam powers at their respective target area locations, and
• providing different respective signal frequency spectrums for at least some of said beams.

A spacecraft broadcast method, comprising:

• broadcasting multiple communication signal beams from a spacecraft to respective non-overlapping target area locations so that at least some of said beams have different sizes at their respective target area locations, and
• providing a common signal frequency spectrum for each of said beams.

A spacecraft antenna array for multi-beam broadcasts to earth, comprising:

• a plurality of antenna reflectors, and
• at least one respective feed horn associated with each reflector,
• said antenna reflectors and their respective feed horns configured to broadcast a plurality of communication signal beams in a non-uniform beam pattern with at least some of said beams having different sizes.
