Pulse-truncated continuous wave (PCW) speed measurement is often used in sonar, but the instability effect of PCW signal in the channel limits the effectiveness of speed measurement. Hyperbolic frequency modulation (HFM) signal is insensitive to Doppler; therefore, HFM signals are widely used in ranging and velocity measurement of sonar and radar. However, due to the filtering effect of the marine environment, the HFM signal of a single frequency band may cause excessive transmission loss, and the echo energy may be too weak to detect the target. Based on the analysis of the influence of speed on the distance measurement of HFM signal, a pulse sequence method based on HFM for speed measurement (PHS) is proposed, which uses HFM signals of different frequency bands and pulse widths in the pulse sequence to perform speed measurement. Extensive simulation results show that PHS method not only guarantees the speed measurement but also makes full use of the energy of the HFM sequence to improve the accuracy of the distance measurement. And PHS method is valuable to the practical application of engineering.<\/jats:p>","DOI":"10.1155\/2024\/6670576","type":"journal-article","created":{"date-parts":[[2024,1,12]],"date-time":"2024-01-12T19:20:05Z","timestamp":1705087205000},"page":"1-11","source":"Crossref","is-referenced-by-count":2,"title":["PHS: A Pulse Sequence Method Based on Hyperbolic Frequency Modulation for Speed Measurement"],"prefix":"10.1155","volume":"2024","author":[{"given":"Tao","family":"Ping","sequence":"first","affiliation":[{"name":"Department of Science and Technology, Qingdao Agricultural University, Qingdao 266109, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3897-7629","authenticated-orcid":true,"given":"Caixia","family":"Song","sequence":"additional","affiliation":[{"name":"College of Science and Information, Qingdao Agricultural University, Qingdao 266109, China"}]},{"given":"Zhiguo","family":"Qi","sequence":"additional","affiliation":[{"name":"College of Science and Information, Qingdao Agricultural University, Qingdao 266109, China"}]},{"given":"Pengmin","family":"Xu","sequence":"additional","affiliation":[{"name":"College of Science and Information, Qingdao Agricultural University, Qingdao 266109, China"}]}],"member":"311","reference":[{"key":"1","volume-title":"Principle of Active Sonar Detection Information","author":"Y.
