IZT And LOG.IN Jointly Announce New Scenario-Based RF Signal Generator

IZT and LOG.IN have today jointly announced the availability of EXERCISE-RF. This new scenario-based RF signal generator is designed for interactive radio frequency testing environments and can generate a real-time radio frequency spectrum. The generated spectrum can be fed into a receiver such as the IZT R3000, a radio monitoring system, and even a geo-localization system based on multi-channel direction finders or Time Difference of Arrival sensors, such as the LOG.IN RMS-DF-5-R3000 with IZT R3000 receivers.

Moreover, the generated RF spectrum can be transmitted through a signal amplifier and an antenna.

EXERCISE-RF allows the creation of complex tactical scenarios with user-defined entities, such as fighters, UAV, ships or soldiers, high resolution 3D terrain, environmental effects and propagation models. The user programs the entities’ behavior via mission doctrines and artificial intelligence and can control its attitude and behavior at all times. A tactical 2D and 3D map with MIL-STD-2525B symbology, a joystick and a throttle are at the user’s disposal.

Within the scenario, one of the entities takes on the role of the Device Under Test, thus virtually representing the entity on which the system to be tested is installed. EXERCISE-RF drives the IZT S1000 to ensure that the DUT is fed with an RF spectrum, which is coherent with the surrounding tactical scenario. To develop the scenario, EXERCISE-RF computes in real time the distance, RF inter-visibility, azimuth and elevation of each of the entities with respect to the DUT. These parameters and the mission doctrines allow EXERCISE-RF to drive the IZT S1000 and decide which signal has to be transmitted on which frequency and with which signal-to-noise ratio. EXERCISE-RF can drive multiple IZT S1000 generators at the same time.

A key feature of EXERCISE-RF is the capability to stimulate multi-channel DFs and TDOA sensors, thereby computing the correct phase and time correlation of each signal in accordance with the DUT and the other entities' positions.

EXERCISE-RF is designed for the radio monitoring sector with a focus on validation and testing rigs, mission planning and mission rehearsal systems, such as validating the COMINT and SIGINT operative capability of a mission platform. EXERCISE-RF can be also used for EW, COMINT, SIGINT or ISTAR training.

With EXERCISE-RF, the user can play, pause, and resume the scenario. He can also record the scenario and play from any given point. EXERCISE-RF is fully Distributed Interactive Simulation and High Level Architecture compliant, which means that it can be integrated into larger distributed-simulation environments.

On the software side, EXERCISE-RF is based on EXERCISE, LOG.IN’s family of modeling and simulation products. The hardware is comprised of a standard computer and one or more of IZT’s signal generator platforms IZT S1000. Since each unit has two independent RF outputs, three generators are needed to stimulate a five channel direction finder.

“Strongly believing in the partnership with IZT and their fantastic staff, we have chosen the IZT S1000 as the signal generator of choice for EXERCISE-RF. By combining 31 independent virtual signal generators in a single platform, the IZT S1000 provides unique flexibility”, said Giovanni Scialanca, Marketing Director at LOG.IN.

“We are happy to partner with LOG.IN, a renowned supplier of technologies for signal processing, direction finding, aerospace software and training systems,“ said Rainer Perthold, CEO of IZT. “The IZT S1000 with its impressive 120 MHz instantaneous bandwidth enables highly complex scenarios and easy simulation of realistic signals for frequency hopping.”

EXERCISE-RF covers a frequency range of 9 kHz to 3 GHz with an instantaneous bandwidth of 120 MHz. Features include multi-channel 3D direction finder testing and a TDOA location-finding platform.

EXERCISE-RF is available from IZT and LOG.IN.
