Classification: CPC G | IPC G

Claim 6:
7. A non-transitory computer storage medium encoded with computer program instructions that, when executed by one or more computers, cause the one or more computers to perform operations comprising:
receiving, from an analog to digital converter, a series of measurements representing frequency samples and spatial samples corresponding to signals obtained from a sensor array, the signals associated with one or more objects in motion that are detected by the sensor array;
generating a plurality of factors by projecting the series of measurements over a plurality of steering vectors corresponding to a range of values of a characteristic associated with the one or more objects, wherein each factor of the plurality of factors corresponds to a measurement of the series of measurements and is weighted by a complex weight corresponding to a factorized polynomial;
combining the plurality of factors to obtain a plurality of values; and
identifying the characteristic associated with the one or more objects detected by the sensor array based on the plurality of values.
