“…(2) In modern radar systems, a radar usually has multiple functions. The radar resources have to periodically or nonperiodically switch to accomplish different tasks, such as target detection, tracking, imaging, and so on [7][8][9]. Then the radar beam can't continuously observe one target, which means that the observation time of the same target is not continuous.…”

“…The filter noise reduction method is mainly based on the statistical characteristics of the signal, and estimates the useful signal from the mixed signal or filters out the noise according to the prior statistical characteristics to improve the SNR. The widely used methods include: Kalman filter [13]; Wiener filter [14]; and adaptive filter [15], etc. However, these types of methods are relatively dependent on the prior information of the statistical characteristics of the signal and noise and have poor noise reduction performance and high computational complexity for non-stationary large bandwidth signals.…”
