Threat Simulation and Verification for Radar Warning Receiver Testing

This application note belongs to a series of application notes which explains how to test EW receivers at RF in the lab with commercial, off-the-shelf signal generators and software. The series will cover all relevant use cases. This application note will discuss threat simulation and verification. Further application notes will address calibration and verification of multi-channel setups for simulation of angle of arrival, generation of radar signals in a hardware in the loop (HIL) environment with PDW Streaming, and automated threat creation and sequencing.

Generation of Radar Signals in a Hardware in the Loop (HIL) Environment

Development of modern EW systems is a complex and expensive process, that requires thorough testing against all requirements during all phases of development. To keep cost under control, system level testing in the lab is key and brings several advantages: test cases can be reproduced under the exact same conditions as often as necessary. System level testing in the lab is often performed in a hardware-in-the-loop (HIL) environment. This application note provides some insight into generating radar signals for hardware-in-the-loop testing with the R&S®SMW200A. An introduction to HIL testing and realtime operation of the R&S®SMW200A is given. The hardware and software interface, the PDW format and synchronization and timing mechanisms are described. Additionally, various example scenarios and detailed information about intermediate calculations are provided. The application note also provides information about system requirements for advanced PDW streaming with multiple emitters on multiple parallel streams.

Radar simulation with modern vector signal generators

Testing radar warning equipment in realistic scenarios is crucial to reliable field performance. This typically involved dedicated instruments or test systems. Commercial vector signal generators (VSG) such as the R&S®SMW200A from Rohde & Schwarz have become a very attractive alternative thanks to their increased available bandwidth and processing power.

Effortless testing of direction finding devices – amplitude based

With the R&S®Pulse Sequencer radar simulation software, users can easily and intuitively create scenarios for simulation of angle of arrival (AoA). Together with multiple coupled R&S®SMW200A vector signal generators, this solution allows quick and thorough performance characterization of all types of direction finding equipment such as devices that use amplitude comparison, interferometric or time difference of arrival (TDOA) techniques. This document describes our test solution for testing devices that use amplitude comparison techniques.

Generate moving emitters in the lab without expensive field tests

The R&S®Pulse Sequencer software offers an easy way to simulate moving radar emitters and a moving receiver for EW receiver tests. The software together with the R&S®SMW200A vector signal generator is a powerful radar simulator. It enables engineers to generate highly dynamic 3D scenarios in the lab.

Import and replay of pulse descriptor words made easy

The R&S®Pulse Sequencer software offers an interface to import lists of pulse descriptor words (PDW). Users can define their specific PDW format in the software before importing the PDW list. The R&S®Pulse Sequencer software automatically uploads the interpreted PDW lists on the R&S®SMW200A to generate the most agile radar signals.

Intelligent modeling of sequences with pulses and waveform segments

The R&S®Pulse Sequencer software offers a powerful mechanism to model sequences that are often required for meaningful radar receiver test cases. The sequences can consist of many individual elements, such as pulses defined by the software or imported waveform segments. The software’s powerful interpulse modulation mechanism gives the user full control of each single element.

Revolutionized pulsed signal generation: easy, intuitive, powerful

The R&S®Pulse Sequencer software together with any Rohde & Schwarz vector signal generator offers an easy and convenient way to generate pulses. For the first time, one package helps you define all the test cases you need in the lab for your entire product development cycle. Test cases extend from simple pulse scenarios for initial component testing to complex 3D radar emitters for acceptance testing of complete systems.

Combining the R&S®Pulse Sequencer software with one of the vector signal generators from Rohde & Schwarz is the perfect solution for defining and playing pulses.

Simplifying Radar Waveform Generation using R&S Pulse Sequencer Software

The need to properly represent the ever changing complexities of the RF environment across communications, surveillance, electronic support measures (ESM) and signal intelligence system (SIGINT) with the advances of signal complexity and bandwidth, requires an enormous test and measurement effort.Extensive field tests are often applied to verify the performance and capabilities under preferably natural but controlled conditions. This is both costly and requires a great deal of time.RF signal environment generation using Test & Measurement equipment brings field tests into the laboratory, where a controlled, cost-effective and reproducible environment exists. The R&S®Pulse Sequencer software is a versatile tool to generate arbitrary and realistic RF signal scenarios ensuringsystem readiness for the real operational world.This application note introduces the R&S®Pulse Sequencer software, explains several examples that are applicable for research, development, before operational and during life-time test in detail, and guides you through the necessary steps, to generate a self-defined, arbitrary real life RF signal environment.
