Multiple signal scenarios like RF Scenario, Acoustic Scenario, Multi-target are generated using MATLAB/LabVIEW as IQ Waveform. IQ-Arbitrary Waveform Generator (IQ-AWG) generates IQ Waveform for programmable transmitted pulse-width, band-widths and center frequencywhich is required for functional & dynamic testing of Signal Processing Hardware like Radar Signal Processing, Sonar Signal Processing and Weapon Communication before actual field testing of the hardware.
Applications
In Air-borne systems such as Synthetic Aperture Radar (SAR) and UAV communication systems to simulate the behavior of returns at the receiver input.
Military Applications ►Intelligence Gathering/Battlefield Reconnaissance/Weapons Guidance.
Civilian Applications ►Topographic Mapping/Geology and Mining/Oil Spill Monitoring/Sea Ice Monitoring/Oceanography/Agricultural Classification and Assessment/Land Use Monitoring/Planetary Investigations.
