초록
본 연구에서는 KRM 모델을 이용하여 남극 은암치의 주파수별 TS를 추정하였다. 실험에 사용된 9개체의 크기는 1.8 - 8.8 cm이었다. 전장에 따른 최대 TS는 38 kHz에서 –92.39 dB, 120 kHz에서 –86.63 dB, 200 kHz에서 85.89 dB이었다. 전장에 따른 평균 TS는 38 kHz에서 –100.0 dB, 120 kHz에서 –93.0 dB, 200 kHz에서 –106.9 dB이었다.
Abstract
In this study, the target strength for multi-frequency (38 kHz, 120 kHz, 200 kHz) of juvenile silverfish (Pleuragramma antarcticum) was estimated using by the KRM (Kirchhoff-ray mode) model. The body shape of the silverfish was described by a picture and the body length of nine individuals ranged in 1.8 cm to 8.8 cm. The maximum TScm according to the total length for the constant term (b20) was –92.93 dB at 38 kHz, –86.63 dB at 120 kHz, and –85.89 dB at 200 kHz, respectively. The averaged TScm according to total length for the constant term (b20) was –100.0 dB at 38 kHz, –93.0 dB at 120 kHz, and –106.9 dB at 200 kHz, respectively.
