radar test systems

Radar Target Echo Simulator is one of its kind systems developed on NI PXI Platform using the Constelli Radar Toolkit for LabVIEW.

The Echo Simulator supports simulation of target echoes for agile monopulse detection and tracking radars using 4-channel coherent simulation for Sum, ΔAz, ΔEl and Guard. Operating in 1 GHz to 18 GHz frequency range with up to 1 GHz of bandwidth, the system is capable of simulating target echoes with Range, Doppler, Radar Cross Section, ECM Features, Antenna Patterns, Net Losses, etc.

Constelli’s Scenario Definition Engine makes the system more sophisticated with trajectory definition for both Radar and Targets in three dimensions. The engine outputs the necessary target characteristics by computing relative parameters between radar and target.

Electronic Warfare Simulation System

A hardware agnostic software suite to simulate environment for EW system tests. The system connects to industry standard simulation software platforms and generates real-time IQ data and works at 1kHz update rate.

Users can define any terrain, platforms, antenna patterns and scan schedule. For all platforms, trajectories can be defined.

Avionics DAQ Applications

UEI platform offers MIL grade rugged DAQ instruments to flight test and instrumentation applications. All measurement needs are covered by COTS modules for fast delivery.

With embedded options, UEI products are easily programmed for DAQ and FTI applications. Rugged design is complete with MIL grade IO connectors to ensure signal integrity.

Our techincal team and partners will help you for cabling and to develop custom embedded software for demanding applications.


Some of the areas we work on.

What is V Diagram?

The V-model is a graphical representation of a systems development lifecycle. It is used to produce rigorous development lifecycle models and project management models. The V-model falls into three broad categories, the German V-Modell, a general testing model and the US government standard. The V-model summarizes the main steps to be taken in conjunction with the corresponding deliverables within computerized system validation framework, or project life cycle development. It describes the activities to be performed and the results that have to be produced during product development.

Handbook: Data Acquisition I/O Applications

UEI’s Applications Handbook, covering data acquisition, embedded I/O, and control, is a 200-page compendium of our design notes and application briefs, and includes a glossary of commonly used DAQ.

Using Accelerometers in a Data Acquisition System

Accelerometers are widely used in industry for measuring vibration in rotating machinery, moving vehicles, aircraft, and in structures. Virtually all accelerometer devices use the force generated by moving a seismic mass to measure acceleration of the mass. The displacement of the mass or the force developed by the motion of the mass is detected and measured by a very wide range of sensors, such as electromagnetic, electrostatic, magnetic reluctance, inductive (LVDT), piezoelectric, piezoresistive, potentiometric, capacitance, strain gauge, servo force-balance and motion-balance, and micromachined semiconductors (MEMS).

Advanced In-Flight Data Recorder

Taking advantage of the small size and high I/O density of a PowerDNA Cube and associated I/O modules, Cessna engineers have designed, built, and tested their new Micro-Pak in-flight data acquisition system in record time. The system is initially being used to collect in-flight near-real-time data from the new Model 162 SkyCatcher™ single engine piston powered, 2-seater, all metal, high wing monoplane. Cessna expects to produce up to 700 SkyCatchers a year at full-rate production. The aircraft will cruise at speeds up to 118 knots and will have a maximum range of 470 nautical miles. It will be capable of Visual Flight Rules/Day/Night operation.

HIL Systems

UEI offers superior hardware-in-the-loop (HIL) I/O for your control, test and monitoring simulations. With solutions designed for aerospace, military, oil/gas, space and more, our robust and flexible HIL offerings ensure application success. We focus on exactly what you need -- from software integration (SIMULINK to C), hardware I/O (avionics, simulated synchro, LVDT, RTD, TC, etc), to signal routing (simulated, real or fault signals) to the device under test. You get the right system and unmatched support from UEI.


UEI’s systems are perfect for many types of engine test applications. Whether you are collecting dynamic high-speed data monitoring vibration or lower-speed monitoring of temperature and strain, UEI has your application solution covered. Control your FADEC with ARINC-429 or MIL-STD-1553 to ensure your signals and sensors are valid. When you need to collect your signals accurately, you can rely on UEI!

UEIDAQ Quick Reference Guide

Awesome guide for products, services and applications of UEI platform. UEI systems are deployed in a wide variety of configurations – including I/O slaves under control of a host PC, fully stand-alone data loggers or embedded controllers – and even as a hybrid, running applications locally, but taking direction from (or sharing data with) a host PC on the network.
