Detection modes - sonarSensor vs radarSensor

Hello all!

In the sensor fusion and tracking toolbox, I am using the sensor and emitter platforms, specifically sonarEmitter and sonarSensor. My project is about using a bistatic system to track UAVs in the air with a set of 1 sonar emitter and 4 sonar sensors.

I am using the example TrackingUsingBistaticRangeDetectionsExample as a guide but apparently there is a bistatic supporting function for radar (which is used in the example) but there is no such thing for sonar, there are only passive and monostatic detection modes.

I have to ask if there is any way to continue with this project because it is urgent and we HAVE to use a bistatic system for our sonar sensors.
