---|---|---|---|---|---|
1 | Skywave Doppler-PrimaryPrimary (Xm-Sky-Tgt-Sky-Rc) | Skywave Doppler-PrimaryPrimary (Xm-Sky-Tgt-Sky-Rc) | Real Number | Frequency | The Skywave Doppler-PrimaryPrimary shift is the offset in frequency between the transmitted frequency and the received frequency for the signal path from the transmitter, off the ionosphere, off the target, off the ionosphere, and then back to the radar receiver. This path could include one or more hops both to and from the target. |
2 | Skywave Doppler-PrimarySecondary (Xm-Sky-Tgt-GndSky-Rc) | Skywave Doppler-PrimarySecondary (Xm-Sky-Tgt-GndSky-Rc) | Real Number | Frequency | The Skywave Doppler-PrimarySecondary shift is the offset in frequency between the transmitted frequency and the received frequency for the signal path from the transmitter, off the ionosphere, off the target, off the ground near the target, off the ionosphere, and then back to the radar receiver. This path could include one or more hops both two and from the target. |
3 | Skywave Doppler-SecondaryPrimary (Xm-SkyGnd-Tgt-Sky-Rc) | Skywave Doppler-SecondaryPrimary (Xm-SkyGnd-Tgt-Sky-Rc) | Real Number | Frequency | The Skywave Doppler-SecondaryPrimary shift is the offset in frequency between the transmitted frequency and the received frequency for the signal path from the transmitter, off the ionosphere, off the ground near the target, off the target, off the ionosphere, and then back to the radar receiver. This path could include one or more hops both to and from the target. |
4 | Skywave Doppler-SecondarySecondary (Xm-SkyGnd-Tgt-GndSky-Rc) | Skywave Doppler-SecondarySecondary (Xm-SkyGnd-Tgt-GndSky-Rc) | Real Number | Frequency | The Skywave Doppler-SecondarySecondary shift is the offset in frequency between the transmitted frequency and the received frequency for the signal path from the transmitter, off the ionosphere, off the ground near the target, off the target, off the ground near the target, off the ionosphere, and then back to the radar receiver. This path could include one or more hops both to and from the target. |
