Coast–Ship Bistatic HF Surface Wave Radar: Simulation Analysis and Experimental Verification

open access: yesRemote Sensing, 2020
The coast−ship bistatic high-frequency surface wave radar (HFSWR) not only has the anti-interference advantages of the coast-based bistatic HFSWR, but also has the advantages of maneuverability and an extended detection area of the shipborne HFSWR.

Speaker Verification Experiments [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1971
Speaker verification is defined as confirming a speaker's purported identity. The method of confirmation is to compare a speech sample of the person against his speech profile, which is based on previous utterances of the same phrase. Experiments have demonstrated the feasibility of an automated scheme of speaker verification under certain restrictions.
