| STORM CORE (km) |
PULSE DURATION (nanosec) |
RANGE GATE (m) |
NUMBER of SAMPLES |
ROTATION RATE (deg/sec) |
BEAM SPACING (deg) |
|---|---|---|---|---|---|
| < 50 | 333 | 250 | 64 | 12 | 0.8 |
| 50-90 | 500 | 200 | 90 | 9 | 0.8 |
| 90-150* | 1000 | 150 | 128 | 6 | 0.8 |
| * This is also the normal PPI operating mode with no range integration. When shorter pulse durations are used, range integration is done to achieve the listed range gate spacing. For RHIs the rotation rate could be reduced by a factor of two resulting in a beam spacing of 0.4 deg. | |||||
