Test your systems to the limit
Radar Environment Simulators (RES®) and Radar Target Generators (RTG) are highly specialized tools for extensive radar testing. This equipment allows to test systems to their absolute limits in lab and factory settings and can be used on-site for in-depth verification of system performance. They are the preferred tools for compliance and acceptance testing.
- Simulate complex scenarios
- Avoid radar downtime
- No (or at least far less) expensive test flights
- In-depth system testing

Fake targets, real insights
Radar Environment Simulator (RES®) for MSSR / IFF
The Industry Standard MSSR & IFF Test Equipmentt
The RES® simulates up to 2048 independent MSSR or Mode S targets, ADS-B, FRUIT, reflectors and antenna behavior on RF level. All the signals that would occur in real life situations are injected into the radar, hereby replying correctly to the radar’s interrogation as real transponders would do.
A known reference scenario is presented to the radar and compared to the radar output. It allows a full data link to be tested to its extreme performance limits. It also has AIMS Mode 5 capabilities
Radar Target Generator (RTG) for
PSR
The Radar Engineer’s Favorite Toolo-
The Radar Target Generator (RTG) is designed to generate primary radar returns. It can be used in two different ways: connected to a system under test (in-factory or on-site) for direct target injection or in the field to generate a remote test target.
The RTG will detect and preserve the radar pulse, apply a fixed and highly precise delay and retransmit the pulse with the appropriate power, pulse-width, frequency and Doppler shift. This is a high-fidelity simulation of real targets and allows for precise test scenarios.A
SkyRF® generator
Complex Scenario Generation for IFF and PSR
The SkyRF® Generator offers advanced capabilities for complex scenario generation in both IFF and Primary Surveillance Radar (PSR) domains. It is a specialized configuration of SkyRF®, the widely adopted RPAS-based solution for CNS (Communication, Navigation, and Surveillance) measurements.
By enabling target generation and scenario simulation at altitude, the SkyRF® Generator introduces more efficient and flexible methods for IFF system certification, sensor alignment, and Combat Management System testing, reducing the need for costly and logistically demanding ground-based setups.
