Continuous wave doppler pre-attenuation velocity envelope: a promising tool for the echocardiographic assessment of aortic stenosis [PDF]

open access: yesEcho Research and Practice
Background In this study, we evaluated the utility of the continuous wave (CW) Doppler pre-attenuation velocity envelope as a potential surrogate for pulsed-wave (PW) Doppler-based interrogation of left ventricular outflow tract (LVOT) flow in patients ...

Abnormal myocardial performance index in M-mode color tissue Doppler-echocardiography [PDF]

open access: yesБългарска кардиология, 2020
The myocardial performance index (MPI) is used for global systolic-diastolic left ventricular function and prognosis assessment in patients with heart disease, allowing assessment of the patient‘s current condition and disease development follow-up.

Range-Doppler Sidelobe Suppression for Pulsed Radar Based on Golay Complementary Codes [PDF]

open access: yesIEEE Signal Processing Letters, 2020
To mitigate the interference caused by range-Doppler sidelobes in pulsed radar systems, we propose a new method to construct Doppler resilient complementary waveforms from Golay codes.

Analysis of Range Sidelobe of Pulse Doppler Fuze [PDF]

open access: yesHangkong bingqi, 2022
When attacking cruise missile at ultra-low altitude, the pulse Doppler fuze may appear false alarm at the range sidelobe due to range ambiguity. In this paper, the ambiguity graph and the sea echo characteristics of the pulse Doppler fuze are analyzed ...
