Radar Geometry
Computes the positions, velocities, and attitudes of the radar and target objects. It also computes the geometric relationships between the radar transmitter and the target, and between the target and the radar receiver. All geometric computations account for the light speed delay of the signal propagation.Available for these objects: Access
Restrictions: Access - Applies when one object is a Radar.
Type: Time-varying data.

Data Provider Elements
| Name | Dimension | Type | Description |
|---|---|---|---|
| Access Number | Unitless | Integer | The number of the current access interval from the list of access intervals. |
| Time | Date | Real Number or Text | Time. |
| Range Sum | Distance | Real Number | Sum of the range for the radar. |
| Closure | DopplerVelocity | Real Number | Average of the radar transmitter-to-target range-rate and the target-to-receiver range-rate. Closure is positive for a target moving towards the radar and negative for a target moving away from the radar. |
| MLC Velocity | DopplerVelocity | Real Number | Main Lobe Clutter (MLC) Velocity is the component of the relative velocity of the target along the radar receiver cone angle. |
| Rcvr Range | Distance | Real Number | Range of the radar receiver from the target |
| Rcvr Prop Time | SmallTime | Real Number | Signal propagation time from the target to the radar receiver |
| Rcvr Range Rate | DopplerVelocity | Real Number | Range of the radar receiver from the target |
| Rcvr Angle Rate | AngleRate | Real Number | The rate of change of the angle of a cone carved by the radar receiver to the target relative position vector and the radar receiver velocity vector. |
| Rcvr Cone Angle | Angle | Real Number or Text | The angle of a cone carved by the radar receiver to the target relative position vector and the radar receiver velocity vector. |

| Xmtr Prop Time | SmallTime | Real Number | Signal propagation time from the radar transmitter to the target |
| Xmtr Range Rate | DopplerVelocity | Real Number | Rate of change for the Range from the radar transmitter to the target |
| Xmtr Angle Rate | AngleRate | Real Number | Radar transmitter angle rate from the target to the transmitter |
