System Properties reports all the
settings in the Radar Basic->System property page.
| 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. |
| Antenna Type |
Unitless |
Text |
Reports out which antenna type has been
selected(i.e. Pencil Beam, Gaussian, Parabolic, Aperture, Dipole,
etc.) |
| Receiver |
Unitless |
Text |
Type of Receiver. |
| Wavelength |
SmallDistanceUnit |
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 |
FrequencyUnit |
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 |
PowerUnit |
Real Number |
This is 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 |
RatioUnit |
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 |
RatioUnit |
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 |
RatioUnit |
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. |
