A device for determining the range of a moving object, the device including at least one sampler, a multi-process array coupled with the sampler, and a selector coupled with the multi-process array, the sampler producing a plurality of sampled signals by sampling a received signal respective of a sequence of pulses transmitted toward the moving object, the multi-process array running a plurality of processes, each of the processes associated with one sampler, each of the processes associated with a respective time shift which is determined according to a respective radial velocity assumption of the moving object with respect to the device and with the pulse rate of the sequence of pulses, each of the processes producing a signal summation by sequentially shifting the sampled signals by the respective time shift and adding together the sampled signals, the selector determining the range according to at least one signal summation which includes a summed pulse event. |
