Techniques are provided for detection and acquisition of signals. A methodology implementing the techniques according to an embodiment includes correlating an input signal with a code sequence at a first plurality of frequency offsets and generating a first bit vector representing locations of correlation detection peaks for each of the first plurality of frequency offsets; correlating the input signal with the code sequence at a second plurality of frequency offsets and generating a second bit vector representing locations of correlation detection peaks for each of the second plurality of frequency offsets; and generating a combined bit vector and accumulating the combined bit vectors over time. The method also includes identifying two consecutive correlation detection peaks in the accumulated combined bit vectors that are separated by a number of bit locations that correspond to a selected range of Doppler offsets; and generating a signal acquisition detection in response to the identification.
