Excessive TX-RX Coupling or Reflection can Lead to Saturated RX Output
If there is excessing TX-RX coupling or chassis reflection, it can lead to a saturated RX output. This situation can occur if the RX input is stronger than -10dBm.
Improve TX-to-RX antenna isolation on PCB. Radome/chassis should give low reflection amplitude and should be as close as possible to the sensor, to reduce the IF frequency.
