The LC tank circuit may include a sensing coil, a first tank capacitor, and a second tank capacitor. Further, the LC tank circuit may alternate between the first tank capacitor and the second tank capacitor, and the power supply may power the LC tank circuit. The target detection system may further include measurement circuitry to measure a first decay characteristic of a first set of free oscillations from the first tank capacitor and a second decay characteristic of a second set of free oscillations from the second tank capacitor. Additionally, the target detection system may also include processing circuitry to compare the first decay characteristic to the second decay characteristic to determine a presence and a distance of a target."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Inductive sensing systems and methods based on multiple frequencies","description":"A target detection system may include a power supply and an inductor capacitor (LC) tank circuit.
