Legacy Control Electronics Redevelopment

Project Overview

SOENCO was tasked with developing a replacement for an obsolete power and control unit used within a legacy ground-based radar system. The original electronics had been in service for decades, replacement assemblies were increasingly difficult to obtain, and much of the original engineering documentation was incomplete or no longer available.

Starting with existing production hardware, SOENCO reverse engineered the assembly to reconstruct the electrical design, document its interfaces, and determine the functionality required by the radar system. Obsolete and unavailable components were identified and replaced with modern alternatives while preserving the existing power, signal, mechanical, and control interfaces.

The resulting design provided a form, fit, and functional replacement for the original unit without requiring modification of the surrounding radar equipment. Updated schematics, design files, bills of materials, and manufacturing documentation established a new engineering baseline for continued production, maintenance, and future revisions.

Engineering Challenges

1
Missing technical documentation
Original schematics, design files, component specifications, and manufacturing documentation were incomplete or unavailable.
2
Legacy system compatibility
Replacement hardware needed to preserve existing electrical interfaces, control behavior, and system interactions without requiring changes to the surrounding platform.
3
Obsolete and unavailable components
Legacy devices were discontinued, unsupported, or impractical to source for future production and maintenance.
4
Existing platform constraints
Replacement electronics needed to operate within the established mechanical, electrical, power, and interface requirements of the fielded system.
5
Maintainable engineering baseline
The redesigned hardware and recreated documentation needed to establish a maintainable technical baseline for future production, troubleshooting, and revision.

Engineering Highlights

1
Complete hardware reverse engineering
Existing assemblies were analyzed to reconstruct schematics, interfaces, circuit functionality, and critical system behavior.
2
Form, fit, and functional replacement
New electronics were developed as a direct replacement for the legacy assembly while preserving its interfaces with the existing platform.
3
Component modernization
Obsolete and unavailable components were replaced with supportable alternatives while maintaining required system functionality.
4
Recreated engineering documentation
New schematics, design files, bills of materials, and manufacturing documentation established a maintainable engineering baseline.
5
Production and lifecycle support
The replacement design established a practical basis for continued manufacturing, maintenance, troubleshooting, and future revisions.
