Definitions
- the FI! ⁇ 3/1 ⁇ 3 detectors 106 are set by the drawing address generator 105 on the correlation processing image memory 108 during one rotation of the sweep (radar antenna 1). The first time or the last time that the sweep accesses each pixel of the orthogonal coordinate system is detected, and any one of these times is given to the correlation data generation unit 107. Since it is necessary to limit the updating of each pixel of the image memory for scan correlation processing to only once per rotation of the sweep, the FIRST signal or the LAST signal is used as this timing.
- the above-described problem occurs due to the time required for rotating the number of antennas.
- the image to be suppressed may be enhanced, and the image to be enhanced may be suppressed.However, when such a state is determined and the processing content is changed to the optimal one In addition, a predetermined time is required as described above.
- a signal output at the timing of FIRST is referred to as a “FIRST signal”.
- the addition / subtraction is performed when a (scan correlation processed image data) ⁇ b (display image data—evening)
