<p>Signals are transmitted from the transmitter (410) using the antenna (420) that is shared with the receiver (430). Return reflected signals are passed from the receiver (430) to a low pass filter (440) and an analogue to digital converter (450). The digital output of the analogue to digital converter (450) is transformed into the frequency domain by the coherent integrator (460) to form FFT templates of the return signals. Signal manipulation and computation signals can be stored in and retrieved from the memory (470). The signal processor (500) discards signal phase, performs presums, forms an FFT matrix of the FFT templates, and analyzes acceleration bins to detect a target object.</p> |
