Direct conversion Doppler radar has the capability to remotely monitor human respiratory activity in a non-contact form. However, the motion or movement from the subject will degrade the acquired respiration signal. As the respiration pattern is one of the essential parameters in respiratory medicine ...
A Doppler control circuit for a CW or pulse Doppler radar system for monitoring not only the phase shift between echo signals from several targets but also the amplitude difference between the several
The present invention discloses a multi-channel delay-Doppler-dimensional mapping division multiple satellites for a long time image enhancement forming apparatus wherein navigation satellite imaging device and the surface to form a reflecting surface reflecting surface imaging system. 接收机的右旋天线接收...
A typical anticollision radar equipment gives advanced warning of possible collision by detecting the change in frequency between the transmitted signal and its reflected signal. The equipment relies on the Doppler effect which arises when the reflected signal frequency is modified by the relative moveme...
1.1.3The compatibility gap The increasing susceptibility of electronic equipment to electromagnetic influences is being paralleled by an increasing pollution of the electromagnetic environment. Susceptibility is a function partly of the adoption of VLSI technology in the form of microprocessors, both to ach...
and the bandwidth of transmission peaks are attenuation at the same time,which means that the quality of the filter can be improved by using periodical N; 3) with the increasing of the refractive index of medium,the bandwidth of bi-system transmission peaks widen,and the transmission peaks are...
Specify the transmitting and receiving radar antenna orientations with respect to the global coordinates. The transmitting antenna points along the +x-direction and the receiving antenna points close to the –x-direction. Get laxTx = eye(3); laxRx = rotx(5)*rotz(170); Compute the transmissi...
