Trends in Radar Design and TestRadar technology has been a critical capability for flight safety, precision navigation, space applications, and more. To meet future electromagnetic spectral operation requirements, modern radars are being increasingly designed to be frequency agile with cognitive modes while utilizing ultra-broadband active electronically scanned arrays to dynamically adapt to electronic warfare and theever-changing electromagnetic spectrum.Additionally, modern radars are increasinglydesigned with the goal of improved EW resilienceand low probability of intercept (LPI) withmultifunction and cognitive capability, radar, EW,and comms. Due to the increased complexity ofdesigns, finding issues before an open-air rangetest has never been more important. Today, radarengineers are leveraging powerful modeling andsimulation tools to digitally test systems prior tointegration. Most leading radar manufacturersleverage hardware-in-the-loop (HIL) integrationtesting to mitigate risk and find issues in the earlystages of the design cycle. Radar target generation technology is a powerful tool to inject realistic targets into radar systems in the lab or during production test to validate system performance or provide that final functional check before deployment.FIGURE 01Phases of Radar Design Test and EvaluationRadar Target Generation Software OverviewThe Radar Target Generation (RTG) Software includes applications and APIs to help you operate certain models of the PXI Vector Signal Transceiver (VST) as a closed-loop real-time radar target generator. The RTG software works with scenarios calculated in real-time, provided from a file, or generated from a linear motion calculation. With this software, engineers can inject up to four independent targets with configurable range (time delay), velocity (doppler frequency offset), and path loss (attenuation) into a radar for test. In its default personality, the VST is a calibrated RF generator and analyzer. Beyond the standard VST calibration, the RTG software includes a loopback calibration that enables users to apply accurate time delay and attenuation by de-embedding residual and external cabling and fixtures effects. The RTG Software is well suited to basic functional validation of radars, production test, or MRO (maintenance, repair, and overhaul).Applications•Closed-loop real-time target generation•Open-loop spectral and datalink systems test•Programmable signal generation and analysisKey Characteristics Array•Frequency Range: 10 MHz to 21 GHz(22.5 GHz to 44 GHz withfrequency extender)•Signal IBW: 1 GHz•Number of Targets: 4 per channel•Channels Per Chassis: up to 4•Signal Parameters: Delay, Doppler, Attenuation•Maximum Range: 64,000 km•Minimum Range: >1 m in low-latency mode125 m otherwise•Update Rate: 15 kHz (List Mode)1 kHz (Live Mode)•Range Step: 0.8 ns (0.12 m)•Doppler Offset: +/- 2 MHz•Doppler Resolution: <5 Hz•Pulse Width: Unrestricted•Typical Rx to Tx SFDR:68 dBc•Overlapping Targets:YesSupported NI Modules: PXIe-5830, PXIe-5831, PXIe-5832, PXIe-5841System Components• Four independent, overlapping targets• NIST-traceable calibration • Automate test scenarios with Ethernet API or partner IP• FPGA Coprocessor Harness for custom IP integration• Low Latency Mode for close-in targetsVector Signal Transceiver Hardware Capability1. 10 MHz to 21 GHz Fc2. 1 GHz IBW3.
