SCR4

System Overview

The SCR4 is Goleta Star's latest and most field-optimized radar platform. Where earlier systems were adapted for UAV integration, the SCR4 was conceived from the ground up as a drone-native sensor — with a form factor, power budget, and operational profile that reflects how modern UAV operators deploy in the field. At 3 pounds and 4×8×8 inches, with a development target approaching 2 pounds, the SCR4 fits naturally into a wide range of current commercial and government drone platforms.

The system delivers 5-kilometer Ka-band radar range at 40 watts — a balance of detection performance and power efficiency that supports the extended mission endurance that drone operators increasingly require. The extended battery life design is a direct response to operator feedback from real-world deployments.

Radar Data Collection Services

The SCR4 is Goleta Star's primary platform for radar data collection services — a growing service offering for government agencies and industry clients who require high-quality SAR imagery for algorithm development, sensor validation, intelligence preparation, and mission planning. Collected radar imagery is delivered alongside corresponding optical reference data, including co-registered Google Earth imagery where applicable, enabling direct comparison between radar and electro-optical coverage of the same scene.

This service-oriented deployment model has informed the SCR4's design at every level: streamlined mounting, field-serviceable components, and a data architecture that minimizes post-flight processing time. The result is a system that produces mission-ready imagery efficiently and repeatedly across varied terrain and weather conditions.

Capabilities

• Single-channel Ka-band (35 GHz) synthetic aperture radar
• 5 km operational range
• 40 W RF output with extended battery life optimization
• Drone-native 4×8×8-inch form factor, ~3 lbs
• Radar data collection services for government and commercial clients
• SAR imagery paired with optical reference data
• Rapid field deployment and reconfiguration

Why SCR4

The SCR4 fills a gap between the higher-capability LUAVR and LCLPR systems and the miniaturized DCR — offering mid-range performance in a package designed explicitly for the operational tempo and platform diversity of today's drone programs. For organizations that need repeatable, reliable radar imagery without the overhead of a large-format airborne system, the SCR4 represents the most accessible entry point into Goleta Star's radar capability.
