Receive modes
- Single-channel receiver
- Used only for alternating transmission. The receiver typically receives the co-polarized radiation (transmit H and receive H, then transmit V and receive V).
- Dual-channel receiver
- Receives in 2 channels (H and V) simultaneously.
The following table summarizes the transmit and receive cases, and the polarization variables that are available for each.
The fixed, dual-channel cases allow the optional dual-polarization cross-polarization LDR and the co-pol/cross-pol correlation amplitude and phase to be measured (for example, RhoH and PhiH).
 |
Standard parameters are available for all cases (dBT, dBZ, V, and W). RVP10 supports all these cases. |
| Receiver type | Transmitter type | |||
|---|---|---|---|---|
| Fixed H | Fixed V | Alternating H and V | Simultaneous H+V | |
| Single-channel | Single-polarization radar | Single-polarization radar | ZV, ZHV, Zdr, RhoHV PhiDP, Kdp | N/A |
| Dual-channel | LDRH, RhoH, PhiH | LDRV, RhoV, PhiV |
The alternating transmission, dual-channel receiver allows both the co-pol and the cross-pol measurements to be made. It is the most complete. ZV, ZHV, LDRH |
The simultaneous H+V transmission and dual-channel reception (also called the STAR mode for simultaneous transmit and receive). This allows the co-pol measurements to be made (Zdr, RhoHV, PhiDP, Kdp). ZV, ZHV, Zdr, RhoHV, PhiDP, Kdp (STAR mode) |
