This reference design has two sets of specifications because the radar is used as a multi-mode radar. MIMO is the first specification. TX beamforming (TXBF) is the second specification,
| PARAMETERS | SPECIFICATIONS (MIMO) | SPECIFICATIONS (TXBF) | DESCRIPTION |
|---|---|---|---|
| Maximum Range | 150 m | 350 m | This represents the maximum distance that the radar can detect an object representing an RCS of approximately 10 m2 |
| Range Resolution | 60 cm | 150 cm | Range resolution is the ability of a radar system to distinguish between two or more targets on the same bearing but at different ranges. The resolution is configurable, so the provided number is just an example. |
| Azimuth Angle Resolution | 1.4 degrees | 1.4 degrees (with multiple beam steering) | Angle resolution is the ability of a radar system to distinguish between two or more targets with the same range and velocity but different angles. The resolution is equivalent in both applications. |
| Elevation Angle Resolution | 18 degrees | n/a | Elevation angle resolution is only available for MIMO application given the antenna design on the TI cascade EVM board. |
| Maximum Velocity | 133 kmph | 133 kmph | This is the native maximum velocity obtained using a two-dimensional FFT on the frame data. For TDM MIMO case, velocity compensation algorithm is applied to recover the native maximum velocity. This specification will be improved over time by showing how higher-level algorithms can extend the maximum measurable velocity beyond this limit. |
| Velocity Resolution | 0.53 kmph | 0.53 kmph | This parameter represents the capability of the radar sensor to distinguish between two or more objects at the same range but moving with different velocities. |
