Lossless and Near-Lossless Voxel Grid Compression Reducing Telemetry Backhaul Bandwidth

Specialized entropy and wavelet encoders compressing 4D radar point clouds by 85% to preserve valuable backhaul capacity.

Sparsity-Exploiting Octree Voxel Encoding

Raw 4D radar cubes (Range x Azimuth x Elevation x Doppler) contain large empty volumes. ISACTelemetry decomposes active reflections into hierarchical Octree trees, transmitting only populated cells.

Near-Lossless Wavelet Quantization

Reflected power values are compressed via integer wavelet transforms and Golomb-Rice entropy coding, reducing backhaul bandwidth from 12 Gbps down to 1.8 Gbps with zero loss of target detection sensitivity.
