The CW system transmits and receives a random waveform while concurrently providing properly delayed phase conversion parameters (ϕi−Θi) from a corrections generator to various range gates. Each range gate processes any echo returns using a most recent phase conversion parameters (ϕk−Θk) provided and correlation of the resulting echo subcodes ϕR produce either target indications or noise signals, depending on the most recent phase conversion parameters (ϕk−Θk) provided to the range gate. The system may transmit the randomly phase-coded CW waveform while recovering any phase code {ϕ1, ϕ2, . . . ϕN} that lends itself to advantageous pulse compressions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Continuous wave (CW) radar system for phase-coded time delayed transmit-receive leakage cancellation","description":"Disclosed is a method, system, and apparatus for transmitting a randomly phase-coded CW waveform in a manner that suppresses signal leakage and enables the recovery of polyphase subcodes advantageous ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10509117","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
