Radar System Testing Guide: Simulation & Analysis Tools
Why Proper Testing of Radar Systems is Critical
Modern radar systems are indispensable for safety and efficiency across countless high-stakes applicationsfrom autonomous vehicles to defence and maritime operations.
Given the complex environments in which these systems operate and their unique advantages in adverse conditionsensuring their reliability and performance through testing is essential. The complex data generated by modern radarsoften from diverse sourcesnecessitates the use of advanced analysis tools to yield actionable intelligence.
Why Traditional Radar System Testing Falls Short
Traditional "live" testing methods for radar systems are often insufficient and present significant challenges. Field trials are expensivetime-consumingand carry substantial safety risksparticularly for defence or autonomous systems.
It is also nearly impossible to consistently replicate specific real-world conditionsincluding variable weatherenvironmental interferenceor unpredictable target behaviour. Modern radar systems can also be susceptible to signal loss and interference. Inadequate testing risks poor performanceregulatory non-complianceand catastrophic real-world failures. Failing to meet regulations can lead to costly development delaysexpensive redesignsor even product bans from key markets.
Earlycomprehensive digital testing is crucial for faster market delivery and a competitive edgeminimising surprises in expensive field trials.
Transforming Testing with Simulation and Analysis
The challenges of traditional radar testing have led to a significant shift towards advanced simulation and analysis. This modern approach offers a powerful way to comprehensively and efficiently validate radar systems.
Radar simulators mimic the behaviour of real-world radars and targets under a vast array of conditions. Simulation softwarepaired with hardware to generate realistic radar outputscan provide radar systems with a consistentcontrolledand repeatable test environment.
The adoption of simulation offers many clear business advantages: cost savingsrepeatabilityenhanced safetyand accelerated development. Simulators can replicate complex scenarios like varied weatherterrainhundreds of targetsand jammingpushing performance limits.
Complementing simulationradar recording and analysis tools can capture and interpret raw dataproviding the insights needed to develop highly reliable systems.
The Solutions for Radar-based System Testing
Cambridge Pixel offers a comprehensive suite of integrated tools designed to transform radar system testingmoving from costlyunpredictable live trials to efficientrepeatableand insightful laboratory-based simulation and analysis.
SPx Radar Simulator creates highly realistic multi-radarmulti-target scenarios. It allows you to test and develop radar display systemsconfigure sophisticated trackersand even train operators without needing actual radar data. It generates convincing radar returns based on real-world terrainuser-defined targetsand environmental factorsoutputting synthetic radar videonavigation dataand target data as separate network streams for real-world client applications.
HPx-310 Radar Signal Output Card is a crucial hardware component that bridges software simulation to physical radar systems. Under software controlthis PCI Express card generates realistic radar signalsincluding videotriggerand azimuth datasignificantly reducing reliance on expensive live radar sources.
RDR Data Recorder provides a robustmulti-channel solution for capturing and replaying a wide array of real-world sensor data. It can simultaneously record radar videoradar tracksAISADS-BIFFand navigation data within a synchronised file structure. This is invaluable for post-mission analysisdebugging system anomaliesand assessing performance under specific conditionsas well as for regression testing.
SPx Video Simulator is designed to simulate camera video and control for developmenttestingand training purposes. It generates realistic video streams by rendering a customisable 3D-modelled scenewhich can include moving targets and terrain. The output video is constructed in real-time based on the camera's position and orientationdepicting the view from the camera. Like real camerasthey respond to standard Pan Tilt Zoom (PTZ) control commands and output video streams. It can integrate with SPx Radar Simulator to define and manage scenarios involving moving targetscreating a unified simulation of both radar and video displays.
SPx Open Access provides engineers and researchers with simplifieddirect access to recorded radar video data for in-depth analysis and new algorithm development. It provides libraries and supporting tools that streamline this accessallowing users to decode recordings created by Cambridge Pixel applications and integrate with environments like C++,.NETand MATLAB.
SPx Monitor is a specialised software application designed to save time aand resources when identifying system issues. It monitors and displays the health and status of SPx-based programs running on the network.
