Workspace.measurement_sensorAddSimpleRadar(self, measurement_sensor: ArrayOfSensorObsel = self.measurement_sensor, measurement_sensor_meta: ArrayOfSensorMetaInfo = self.measurement_sensor_meta, radar_range_limits: Matrix = self.radar_range_limits, freq_grid: AscendingGrid = self.freq_grid, pos: Vector3, los: Vector2, pol: Stokvec = [0.5, 0.5, 0, 0], range_bins: AscendingGrid) → None

Adds range-resolved pencil-beam radar observation elements.

For every frequency in freq_grid, one observation element is appended for every interval in range_bins. The ordering is frequency first and range bin second, matching the ARTS2 yRadar convention. All generated elements share their frequency and position/LOS grids. The matching limits are appended to radar_range_limits, and measurement_sensor_meta receives one range grid per frequency.

The receiving polarization is a Stokes dot-product vector. For example, [0.5, 0.5, 0, 0] is the old ARTS polarization index 5 (vertical linear).
