Considering the target Doppler frequency and spatial cone angle uncertainties are present, we formulate the averaged signal-to-clutter-plus-noise ratio (SCNR) as the optimization goal. Specifically, the averaged
4) clutter noise ratio 杂波噪声比5) signal-to-noise ratio 信号噪声比 1. To increase signal-to-noise ratio(SNR) of medical ultrasound image,a frequency-modulated(FM) ultrasound transmitted imaging method is developed,where a weighted linear FM ultrasound is transmitted to enhance the emission ...
In addition to the signal-to-clutter-plus-noise ratio (SCNR), we also consider the filtered integrated sidelobe level (ISL) and optimize these two metrics simultaneously. It is assumed that cognitive radar can obtain environment information based on database and prior return. We relate the SCNR...
Long coherent processing intervals (CPIs) can bring better resolution and signal-to-clutter-plus-noise ratio (SCNR). Due to the change in the effective rotation vector (ERV), the conventional Range-Doppler (RD) algorithm is not appropriate for producing a well-focused image. To resolve the ...
