1. A method for processing signals from a plurality of groups of sensors, each group including a first sensor and at least one additional sensor, the method comprising:
receiving sensor data from each of the plurality of groups of sensors, the plurality of groups of sensors being on a single mobile sensor platform;
calibrating the sensor data for each of the plurality of groups of sensors, the calibrating including calibration information specific to the sensor data for each of the plurality of groups of sensors, wherein the calibrating of the sensor data comprises:
determining a correction factor for the first sensor of each of the plurality of groups using at least one calibration table, the at least one additional sensor and additional sensor data from the at least one additional sensor associated with the first sensor in the at least one calibration table; and
providing corrected sensor data for each of the plurality of groups based on the sensor data and the calibration information, the corrected for the first sensor being specific to an environment of each of the plurality of groups on the single sensor platform, wherein the providing of the corrected first sensor data further includes:
aligning sensing times of the first sensor data and another sensor data in each group to obtain aligned first sensor data; and
applying the correction factor to the aligned first sensor data for each of the plurality of groups.
