The problem is to extract as much information as possible from the vessel motions and their spectra in the frequency domain. The estimation process is summarized as follows: 1. Calculate the vessel motion RAOs offline by using seakeeping codes; 2. Obtain the vessel motion signals, transfer the ...
The FPGA implementation of the acquisition is shown in Figure 9. The Nios II processor is used to manage and configure the different blocks (e.g., the acquisition module is configured with parameters such as Doppler frequency, PRN code, number of integrations, etc.), and to analyze the data...
