Automated Testing and Simulation Solutions for Radio Frequency applications

Mobile Testing Measurement POD (RF ATE), the mobile solution to measure and test Radio Frequency

The Mobile Testing POD developed by SDSI is the India’s first mobile vehicle-based RF measurement and test system. In operation, the vehicle moves around aircraft to perform Go/No-Go Tests on sub-systems. It includes GPS synchronized generation of analog, digital communication and RADAR signals.  

The typical features than can be supported:  

• Testing & Evaluation of Primary Radar & Secondary Surveillance Radar 
• Testing of all sensors of ESM/ RWR system of Airborne surveillance system 
• Testing of CSM and Datalink Sub-Systems CBDL and KBDL of Airborne surveillance system. 
• Testing VUHF communication (with NI - PXI Instrumented in vehicle) 

TCE, Telemetry Channel Emulator: a complete simulation solution for telemetry systems

The TCE offers a solution that simulates the flight profile and propagation effects, acting as a virtual channel, so that the various parameters of the telemetry system can be adjusted to optimal levels for achieving the desired performance and finding any faults that are present.

It takes Inputs like PCM Encoder, Baseband/ IF Signal 70MHz, PCM Simulation and gives Outputs Signal in multiple frequency bands (L, S, C and X) as per the modulation scheme and link parameters, emulate channel effects between airborne transmitter and receiver and produce a resultant RF signal for feeding to subsequent processing by real-world telemetry receiving subsystems. 

Secondary Surveillance Radar Rx/Tx Test solution

SDSI, ATE for secondary surveillance radars is created using NI PXI modular instruments and LabVIEW. This system saves 90% of the radar testing time compared to the manual connections of previous desktop instruments. It also saves 60% of the cost compared to other ATEs built with traditional instruments. The system supports different types of tests such as receiver tests (Dynamic Range, Bandwidth, Operational Sensitivity…) but also transmitter tests (Out Power, Out Power Mode & PRF Stability, Output Power Selection & Sectorization...).

Furthermore, the ATE allows different simulations such as Antenna Simulation (North Marker, Pulse Generation, and Azimuth Count Pulses Generation) and Target Signal Simulation (Single Target, Stationary Target, Trajectory Motion, and Multiple…).
