Low-Power Inference for Embedded ISR: A Field Report

Eighteen months of deploying inference engines on constrained platforms has taught us where the power budget actually goes — and it's not where most neural architecture papers assume.

Human-on-the-Loop: Design Patterns for Supervised Autonomy

The phrase 'human in the loop' is overloaded and underspecified. We distinguish four distinct supervisory patterns and discuss when each is appropriate for autonomous ISR platforms.

A Practical Architecture for Multi-Modal Sensor Fusion on Autonomous Platforms

Fusing EO/IR, radar, and acoustic sensor streams on a resource-constrained platform requires careful timestamp alignment, cross-modal uncertainty weighting, and graceful degradation.

SWaP Tradeoffs in Edge AI Hardware Selection

Jetson Orin, Hailo-8, Myriad X, custom FPGA — every edge compute platform involves a different point on the latency / power / cost curve. We document the tradeoff space for mission-critical ISR payloads.

mmWave Radar in Contested RF Environments: Design Lessons

mmWave radar offers sub-centimeter resolution in low-visibility conditions, but contested electromagnetic environments introduce interference patterns that most commercial radar stacks don't anticipate.

Latency-Constrained Neural Inference for UAS Payloads

When an unmanned aircraft has 40 milliseconds to classify a target and can't call home, every compute cycle matters. We walk through our approach to sub-50ms inference under real SWAP constraints.
