The time of arrival (TOA) or time difference of arrival (TDOA) beteen two signals are seen extensively in literature. Are these algorithm applicable for point target as well as extended target? For example correlation based TDOA is applicable for extended target or not? Any clarification would be highly appreciated.

  • $\begingroup$ What shape are the extended targets? $\endgroup$ – Olli Niemitalo Sep 23 '15 at 4:51
  • $\begingroup$ @OlliNiemitalo Will it be shape dependent? $\endgroup$ – Creator Sep 23 '15 at 4:53
  • $\begingroup$ Would be easier to try it out (perhaps symbolically) on a clearly defined shape such as a constant-density line segment. If the target has a center point such that rotation around it has no effect on the peak time or the average value of the impulse response, then that might translate to a working correlation-based algorithm. Also how large are the targets compared to their distances and what kind of resolution do you need? $\endgroup$ – Olli Niemitalo Sep 23 '15 at 5:09
  • $\begingroup$ @OlliNiemitalo Thank you for your interest. I am asking if there are such difference exist in literature. I do not have a specific problem but would like to if the problem is analysed from this view point. $\endgroup$ – Creator Sep 24 '15 at 3:12
