Problems solved by technology

[0003] The waveform generation of modern radar systems usually adopts direct digital synthesis, including two different implementation methods based on phase accumulation and direct reading based on waveform storage. The types of waveforms output by the front end are usually fixed and limited, and the support for complex modulation patterns is not flexible. The latter has high real-time requirements for software calculation and data transmission, which increases the complexity of the radar system.
