The phase shifters are driven by digital phase accumulators. The system does not need or use DACs, sine/cosine tables, balanced modulators and mixers and, instead, implements phase shifters as modulators to create the transmit signal and to de-ramp the incoming signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Linear FM pulse modulation and stretch demodulation in radar using quadratic spinning phase shifters","description":"A stretch processing system uses phase shifters to produce a transmitted LFM-ramped signal and a local oscillator signal used to demodulate an LFM-ramped received signal.
