FMCW Baseband Waveform

< Technical Principles and Characteristics >

Design variables such as frequency, phase, amplitude, Doppler bandwidth, etc. to be applied to generating FMCW signals (center frequency: 90MHz, bandwidth: 10MHz) by digital direct synthesis (DDS) method are derived through simulation according to radar operation requirements.
Key technologies related to circuit design, timing control, transmission/reception synchronization, etc. required for digital signal synthesis.
Design flexibility can be improved by changing software for frequency, phase and amplitude modification.
Suitable for generating various types of pulse-type waveforms such as pulse Doppler radar.
