# Roadmap

Planned and potential extensions include:

## Environmental modelling

- Coherent ambient noise modelling for wind, rain, and wave-induced noise
- Improved acoustic volume attenuation and boundary loss modelling
- Systematic environmental uncertainty modelling for sound speed and sensor-position errors

## Signal and source modelling

- Expanded source directivity modelling
- Additional sensing geometries, including hull-mounted arrays, sonobuoys, and distributed arrays

## Detection and performance analysis

- Alternative SNR and beam-power outputs, including angle-dependent CFAR variants
- Bearing × time × frequency output volume to support multi-band downstream processing
- Multi-band detector operating across frequency bands simultaneously
- 2D CFAR with training cells spanning both bearing and time, giving the detector access to a limited time history

## Extended sensing modalities

- Active sonar modelling
- Multistatic and bistatic configurations
