Hi,
I was recently involved in testing of Electro optical pod (It had a IR sensor alongside a CCD and an LRF). We were assessing the detection and recognition ranges for this equipment using a target with appropriate IR emission for the test. Since we had to make sure that the assessment was for the 'right' target, we used to 'zoom in' to locate the target and then adjust the zoom level (as in the test order) of the respective sensor for detection and recognition criteria assessment. As this helicopter mounted equipment approached the target, the assessment was made for the ranges corresponding to the zoom level at which detection and recognition was possible.
In this procedure mentioned above, I feel that the ranges of assessment achieved during the test may be overestimated. This 'overestimation' is in relation to an operational scenario where the pilot/ pod operator will be scanning the in the entire field of view available on the display and not only the exact location where the target has been placed. Therefore, I feel that this test must be done with the requisite zoom level set and the ranges for detection and recognition assessed while scanning the entire field of view. In this case the approximate location of the target will be known, however it would be as near to the operational conditions as we could get for the testing.
I would appreciate comments on my opinion and any more experiences that people in this forum would like to share about testing of Electro optical pods.
