1. A multiple antenna lobe receiving system, comprising:

  • a processor; and

    a memory coupled to the processor and containing program instructions that, when executed by the processor, cause the multiple antenna lobe receiving system toreceive multiple antenna lobe return data from two or more receive channels; and

    track movement of targets using the multiple antenna lobe return data over time;

    wherein the movement is used to provide system calibration data to correct mismatch errors associated with the multiple antenna lobe return data, and wherein an angle-to-target estimate for each target of the targets is provided without servoing an antenna to point to each target and wherein target movement as sensed by the multiple antenna lobe receiving system is compared to a linearized target movement model for each target of the targets to estimate the system calibration data.
