Data Provider Elements
| Name | Dimension | Type | Description |
|---|---|---|---|
| Monostatic | Unitless | Text | Reports out that the radar has been set to use mono-static operation. In Monostatic operation, a common antenna is used for both transmitting and receiving. (Continuous Wave radars are modeled to use identical, co-located antennas.). |
| Transmitter | Unitless | Text | Reports out the radar that serves as the transmitter in a bi-static radar system. Only mono-static radars may serve as the bi-static transmitter. |
| Receiver | Unitless | Text | Type of Receiver. |
| Antenna Type | Unitless | Text | Reports out which antenna type has been selected(i.e. Pencil Beam, Gaussian, Parabolic, Aperture, Dipole, etc.). |
| Wavelength | SmallDistance | Real Number | This field defaults to 10 cm wavelength. If the user has entered another wavelength this will be reported out. This option is available only for Monostatic operation, since, for Bistatic operation, frequency / wavelength is determined by the other radar serving as the bi-static transmitter. |
| Frequency | Frequency | Real Number | Reports out the range of frequencies of those to which the receiver responds. Defaults to a frequency of 2.998 GHz. If the user has entered a desired frequency this value will be reported out. This option is available only for Monostatic operation, since, for Bistatic operation, frequency / wavelength is determined by the other radar serving as the bi-static transmitter. |
| Peak Power | Power | Real Number | The peak output power of the transmitter. It is available only for Monostatic operation, since, for Bistatic operation, peak power is determined by the other radar serving as the bi-static transmitter. |
| Other Gain/Loss | Ratio | Real Number | Reports out the additional gains and losses the user has chosen to apply to the radar. These are the gains and losses that affect performance but are not defined using built-in analytical models. STK allows you to model these by specifying miscellaneous gains and losses that can be added to the equation. |
| System Temperature | Unitless | Text | The system's inherent noise characteristics which either the user has defined or has allowed STK to calculate. |
| Constant System Temperature | Temperature | Real Number | Reports out the user selected constant system temperature value. |
| Receiver Noise Figure | Ratio | Real Number | The noise figure represents the contribution to the total system noise by the gain stages of the receiver. It can be thought of as a factor that describes the noise level in a receiver relative to that in a theoretically perfect receiver. The noise figure is always greater than 0 dB. |
| Transmission Line Loss | Ratio | Real Number | The transmission line loss is the loss of the transmission line between the antenna and receiver. |
| Transmission Line Temperature | Temperature | Real Number | The transmission line temperature is the physical temperature of the receiver transmission line. |
| Antenna Noise | Unitless | Text | Noise that the antenna receivers from radiating bodies within its radiation pattern. Given as a temperature, antenna noise is a function of the direction in which the antenna is pointing, its radiation pattern and the state of the surrounding environment. |
| Antenna Noise - Constant Temperature | Temperature | Real Number | The antenna noise as a constant temperature, specified by the user. |
| Antenna Noise - External File | Unitless | Text | Reports out the filename of the external antenna noise temperature file. The antenna noise temperature can be given in a user-specified file that describes antenna noise temperature (in Kelvin) as a function of the ground elevation angle (in degrees). |
| Antenna Noise - Use Earth | Unitless | Text | Use the Earth as part of the calculation of the system temperature for antenna noise. |
| Antenna Noise - Use Sun | Unitless | Text | Use the Sun when calculating the system temperature for antenna noise. |
| Antenna Noise - Use Atmosphere | Unitless | Text | Use the atmosphere when calculating the system temperature for antenna noise. Available only for a Facility, Place, or Target. |
| Antenna Noise - Use Rain | Unitless | Text | Use rain when calculating the system temperature for antenna noise. Available only for a Facility, Place, or Target. |
| Antenna Noise - Use Cosmic | Unitless | Text | Use the cosmic background noise when calculating the system temperature for antenna noise. Available only for Vehicles. |
| Antenna Noise - Other | Temperature | Real Number | Allows the user to enter noise from other sources for the calculation of the system temperature for antenna noise. |
| Antenna Noise - Plugin File | Unitless | Text | TuserCustomA is the antenna noise temperature component attributed to user defined custom loss model A. |
