Development of Mini-Buoy for short term measurement of ocean wave

Autor: Takehiko Takayama, H. Susaki, Yoshiaki Hirakawa, Tsugukiyo Hirayama

Publikováno v: OCEANS 2016 MTS/IEEE Monterey.

The authors have developed a small wave buoy as “Ultra-Small-Directional-Wave-Buoy” from 1997. In recent years, The demand of short term wave measurement such as verification of wave radar system and speed trials of new ships is increasing, but g

Pulse compression for a simple pulse

Autor: Hiroshi Takase, H. Susaki, Masanori Shinriki

Publikováno v: IEEE Transactions on Aerospace and Electronic Systems. 44:1623-1629

A new pulse compression method for a simple pulse is proposed. The proposed method has a filter with impulse response h(t) whose Fourier transform H(f) is given by D(f)/S(f), where D(f) is the Fourier transform of desired output waveform d(t) and S(f

A fast algorithm for high-accuracy frequency measurement: application to ultrasonic Doppler sonar

Autor: H. Susaki

Publikováno v: IEEE Journal of Oceanic Engineering. 27:5-12

In an attempt to investigate the technical feasibility of a continuous-wave Doppler sonar, we have examined a method of measuring low velocities with a high velocity resolution, or frequency resolution, by use of a simple circuit configuration employ

Property of New Periodic Binary Codes Compressed to Several Chips

Autor: Hiroshi Takase, Masanori Shinriki, H. Susaki, S. Yamashita

Publikováno v: OCEANS 2008 - MTS/IEEE Kobe Techno-Ocean.

The new periodic binary codes, which compress to several chips, are searched in range of code length 50 by computers. We then found many new periodic binary codes with one for peak side-lobe level and zero for all side-lobe, which are different in M-

Application of marine radar for ocean wave monitoring

Autor: Y. Hiraoka, Y. Iwasaki, H. Susaki, R. Hosoda, T. Kojima, T. Yamada

Publikováno v: Oceans '04 MTS/IEEE Techno-Ocean '04 (IEEE Cat. No.04CH37600).

Simple algorithm for acquiring characteristics of ocean waves: such as direction and average length of wave systems, is proposed through analyses of radar echo from sea surface. Method of spectral analysis is applied to original radar echo signals be

Method of high-resolution frequency measurement for pulse-Doppler sonar

Autor: H. Susaki

Publikováno v: Proceedings of the 2002 Interntional Symposium on Underwater Technology (Cat. No.02EX556).

We have studied an algorithm for a Doppler sonar for achieving high-resolution measurement of the velocity of a vessel using the Doppler shift in frequency. This paper proposes a new algorithm for achieving high-resolution velocity measurement by cal
