| Abstract: |
| This paper discusses the role of ocean compensation filter in Super Low Frequenc
y(SLF) receive
r and the design of the ocean compensation filter for SLF communication by bo
th Infinite Impulse Response(IIR) filter with one zero and one pole, and IIR fil
ter with two zeros and one
pole. The zeros and poles are determined numerically. Calculation results show t
hat the implemented filters can well approximate the magnitude of frequency resp
onse of the theoretical ocean compensation filter over 20～200 Hz. The imple
mented IIR filter with two zeros and one pole maintains the amplitude error less
1 dB for 0～130 m depth. It can meet the design requirements of SLF r
eceiver. |
