SAR Properties
Reports settings in the Radar Basic->SAR property page. In order for SAR to be enabled, the radar must be on a satellite, missile or aircraft.Available for these objects: Radar
Type: Fixed data.
Availability: Reports
Data Provider Elements
| Name | Dimension | Type | Description |
|---|---|---|---|
| Enabled | Unitless | Text | Reports out if the SAR (synthetic aperture radar) mode has been turned on. |
| Integration Time | Time | Real Number | Reports out the constraint values applied to integration time - the fixed integration time or time to achieve the desired azimuth resolution, depending on the setting of the analysis mode when defining the radar. |
| Azimuth Resolution | Distance | Real Number | Reports out the constraint values applied to azimuth resolution - the fixed azimuth resolution or the resolution achievable within the desired integration time, depending on the setting of the analysis mode when defining the radar. |
| MNR | Ratio | Real Number | Reports out the multiplicative noise ratio - the contribution of ambiguous range and side-lobe returns to the image formation process. The default value is -20 dB. |
| PRF | PRF | Real Number | Reports out the pulse repetition frequency - range: 0.1 to 1000 kHz. |
| Unambig Range | Distance | Real Number | Reports out the desired target range for which unambiguous data is required. The Range is ambiguous where the true target range is greater than the ambiguous range as computed by radar. The Unambiguous Range constraint denies access when the range is ambiguous (i.e. it enforces a low PRF mode). |
| Az Broad Factor | Unitless | Real Number | Reports out this analysis weighting factor to compensate for signal processing losses in the azimuth dimension when SAR mode is enabled. The default value is 1.2 and can be changed by the user. |
| Rng Broad Factor | Unitless | Real Number | Reports out this analysis weighting factor to compensate for signal processing losses in the range dimension when SAR mode has been enabled. The default value is 1.2 but can be changed by the user. |
| IF Bandwidth | Bandwidth | Real Number | Reports out the IF Bandwidth which is the analog-to-digital sampling rate of the SAR. This bandwidth assumes a quadrature sampling without oversampling; in the case of real-valued sampling the IF Bandwidth must be twice the sampling rate. This rate determines the amount of data that can be collected in a given amount of time. |
| Rng Resolution | Distance | Real Number | Reports out the range resolution, which is inversely related to the pulse-compressed RF bandwidth of the transmitted signal. This is a user-defined parameter that you have to set. |
| Bandwidth | Bandwidth | Real Number | The Receiver Bandwidth. |
| Pulse Compression Ratio | Unitless | Real Number | Reports out the ratio of compressed to uncompressed RF bandwidth if SAR mode has been enabled and this factor has been selected. |
| Pulse Width | SmallTime | Real Number | Reports out the width of the transmitted pulse (the inverse of uncompressed RF bandwidth) if SAR mode has been enabled and this factor has been selected. |
| Scene Depth | Distance | Real Number | Reports out the range swath along the radar line of sight to the target if SAR mode has been enabled and this factor has been selected. |
| Rng Chirp Rate | SARRngChirp | Real Number | Reports out the frequency modulation rate of the pulse compression (1/sec2) if SAR mode has been enabled and this factor has been selected. |
