U.S. Navy sonar towed array of flexible long-term
The same season. Li Xing SQR-J9 voice port to detect than the average number of boats using sonar exploration sQR-l8A Ji I i to 11 times higher using SQR-19 sonar search in the convergence zone. The detection range of up to 65kin; in good hydrological conditions, the best towing speed drag + detection range of up to 100km: In LAMPK3 under the guidance of the helicopter system can achieve 125kin. The United States began in 1974 with the implementation of surveillance towed array sonar system (sURTASs) program. To solve the problem of long-range detection of other submarines. Built long-range sonar. Able to determine in the second, third convergence zone submarine location. The design prototype lasted almost 8 years. New ANFOQQ a 2 (sURrAss) sonar for Towed array which dragged on the 1830m behind the payment. Length of 1220m. Can cover J50 ~ 450m depth. Towed array and the sound of the mouth other than, ANt'UQQ-sound ~ # I (SUR.TASS) can guarantee the most low-frequency noise signal within the receiver. Reported. The distance of the submarine sonar exploration interests of more than 150kin. Sometimes up to 550km. Knowledge �� distance of 140km. Sonar measurements refer to the accuracy depends largely on the sexual characteristics of f Chu 1 + e-forming method with the array has little bit of change to the measuring accuracy of 25. How to reduce the noise of the ship impact on the SURTASS sonar system. Has been conducting the study is the spy problem. Has been equipped with a special filter to filter out the sound + port monitor ships from the scattering noise. Vulnerability is a flexible system SORTASS remote exploration potential of serious flaws in the conflict. First, to destroy each other sonar Zhencha Chuan, to ensure their own security so. SURTASS system is best for the submarine sonar carrier. To effectively reduce the vulnerability of the system. Well to ensure peace during the reconnaissance and covert. SORTASS system sound inlet in J]] of information. First, pretreatment of the ship's side,[link widoczny dla zalogowanych], and then send the information via satellite communications to the shore of one of two information processing center for detailed analysis and processing. Necessary information can be sent directly in place within the region r reconnaissance anti-submarine ships. The information center is on the shore underwater Zhen Chachuan all information and data sent to final processing. In modern low-frequency sonar station on the hydrophone regarded simulates signals into digital signals, using the best crossing-based adaptive filter method to ensure the system works with a high degree of flexibility. In the interference conditions to ensure that r so much the level of provision of a fake 48 - ��[1-N2 small ktvibration. xCT-uniform cross-section rods.

Come to give a bonus shot of variable parameters of the equivalent circuit and income statement for the actual horn that sold the design and calculation of theoretical guidance for Ji l.

This low-lying Wei exploration and trail system in the standard population has a considerable advantage. Difficulties for the transmitted signal in frequency. Way the system withered. Bandwidth and management side and have a strong advantage. Must add that is. In the low frequency signal transmission in the aqueous medium minimal loss. Since the area is mainly in the sacral-frequency noise spectrum of the discrete components. Absorbing coating is no longer so effective was.
