Radar technology is essential for flight safety, precision navigation, space applications, and more. To meet future electromagnetic spectrum operating requirements, modern radars are increasingly being designed to be frequency-flexible with simultaneous perception modes using electronically scanned arrays—ultra-broadband active electronics to flexibly adapt to electronic warfare and the ever-changing electromagnetic spectrum.
Solution Overview
Radar technology is a critical capability for flight safety, precision navigation, space applications, and more. To meet future electromagnetic spectral operation requirements, modern radars are increasingly being designed to be frequency agile with cognitive and multi-modes while utilizing ultra-broadband active electronically scanned arrays (AESA) to dynamically adapt to the ever-changing electromagnetic spectrum. Additionally, modern radars are increasingly being designed with the goal of improving EW resilience and low probability of intercept (LPI) with multi-function and perception capabilities, Radar, EW and Comms.
Due to the increased complexity and cost of designs, finding issues before open-air range test has never been more important. Today, radar engineers are leveraging powerful modeling and simulation tools to digitally test systems prior to implementation. Most leading Radar Manufacturers leverage Hardware in the Loop integration testing to minimize risk and find problems early in the design cycle. The Radar System Simulator is a powerful system for populating real Radar systems in the lab or during production testing to validate system performance or provide final functional testing before when deployed.
The future
The VI signal generation library includes features CW, LFM, NLFM, FSK, SFM, P1, P2, P3, P4, Zadoff-Chu, Frank, with PW and PRI schema configurations.
Radar Simulation Parameters
With easy to use, interactive interface panels for developing and debugging systems, to automatable APIs for deploying both characterization as well as production test systems, the RADAR SIMULATION provides a unified software experience for Radar. In addition to easy-to-use panels, the library also includes support for several development environments including LabVIEW, C, C#, and .NET, as well as for FPGA programming.

Radar Target Generator
The Radar Target Generation (RTG) Driver provides additional functionality for the PXIe Vector Signal Transceiver (VST) for radar system level test. The Vector Signal Transceiver (VST) combines an RF vector signal analyzer and generator with a programmable FPGA and digital interfaces for real-time signal processing and control.
The RTG driver is built on top of the VST as a closed-source, license-restricted, and pre-compiled FPGA personality that allows the VST to operate as a closed-loop, real-time radar target generator. With this driver, 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 testing. In its default personality, the VST is a calibrated RF generator and analyzer. Beyond the standard VST calibration, the RTG driver includes a loop-back calibration, which enables users to apply accurate time delay and attenuation by de-embedding residual and external cabling and fixture effects. The RTG Driver is a great solution for engineers needing to do basic functional validation of radars, production tests, or MRO.
