Digital filters used in sonar signal processors perform two major functions, the filtering of waveforms to modify the frequency content and the smoothing of waveforms to reduce the effects of noise. The two generic types of digital filters are FIR and infinite impulse response (IIR) filters. Visa mer Sonar systems are generally used underwater for range finding and detection. Active sonar emits an acoustic signal, or pulse of sound, into the water. The sound bounces off the target object and returns an “echo” … Visa mer It is really an important part for good system performance in sonar system to have appropriate sensor array and beamformer. To infer … Visa mer Filters and smoothers are used extensively in modem sonar systems. After sampling, the signal is converted from analog signal into a discrete time signal, thus digital filters are only into consideration. What’s more, although some filters are time varying or adaptive, … Visa mer For active sonar, six steps are needed during the signal processing system. Visa mer In modern world, digital computers do contribute a lot to higher speed and efficiency in data analysis. Thus, it is necessary to convert an analog signal into a digital signal by sample the signal in time domain. The operation can be realized by three … Visa mer Bandshifting is employed in active and passive sonar to reduce the complexity of the hardware and software required for subsequent processing. For example，in active sonars the received signal is contained in a very narrow band of frequencies, typically … Visa mer In a word, the goal of the sonar is to extract the informations and data from acoustic space-time field, and put them into designed and … Visa mer WebbSonarScope is highly customizable and provides an original approach to MBES data processing, making it an invaluable tool for researchers and engineers who need to test …
