Abstract
A data collection method uses a receiver having data collection sensitivity to signals originating from objects dispersed in a field that is subject to distortion. The sensitivity of the receiver is swept along a first arc. For each of the objects detected during the sweeping step, two of the signals are collected at two different points in time. A difference between the two signals is compared to a threshold. When the difference exceeds the threshold, the sensitivity of the receiver is re-swept along a second arc that is angularly less than the first arc. When the difference is less than the threshold, the signals are captured.
Claims26
A data collection method, comprising the steps of:
- providing a receiver having a data collection sensitivity to signals originating from objects dispersed in a field that is subject to distortion;
- sweeping said sensitivity of said receiver along a first arc;
- collecting, for each of the objects detected during said step of sweeping, two of said signals at two different points in time;
- comparing a difference between said two signals to a threshold;
- re-sweeping, when said difference exceeds said threshold, said sensitivity of said receiver along a second arc that is angularly less than said first arc;
- and
- capturing said signals when said difference is less than said threshold.
A data collection method, comprising the steps of:
- providing a receiver having a data collection sensitivity to signals originating from a field that is a three-dimensional fluid environment;
- sweeping said sensitivity of said receiver in increments along a first arc;
- collecting, for each of said increments along said first arc, two of said signals at two different points in time;
- comparing a difference between said two signals to a threshold;
- re-sweeping, when said difference exceeds said threshold, said sensitivity of said receiver in increments along a second arc that is angularly less than said first arc;
- and
- capturing said signals when said difference is less than said threshold.
A data collection method, comprising the steps of:
- providing a receiver having a data collection sensitivity to signals originating from a field that is a three-dimensional fluid environment;
- sweeping said sensitivity of said receiver in increments along a circle;
- collecting, for each of said increments along said circle, two of said signals at two different points in time;
- comparing a difference between said two signals to a threshold;
- re-sweeping, when said difference exceeds said threshold, said sensitivity of said receiver in increments along an arc of said circle;
- and
- capturing said signals when said difference is less than said threshold.
