When a PLL is fixed on one of a large number of frequencies developed at a Doppler channel 'S', the frequency is selected and maintained in a range channel 'T2U2 . These frequencies generate radar echoes from a large number of targets, signal echoes returned through a number of paths ...

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 targets and to further provide a phase lock loop which tunes the radar to a particular target ...

A direct-detection Doppler lidar system is demonstrated that uses a CCD as a detector for the first time to our knowledge. The ability to use this linear device with the circular output from a Fabry-Perot etalon comes from use of a circle-to-line converter [Appl. Opt. 29, 1482 (1990)...

Doppler asymmetries have been observed in model tank experiments in the signal received after being scattered from a wind‐driven surface. A distinct spectral shift was observed when the plane containing the transmitter and receiver was perpendicular to the wind direction. This paper examines the conje...

The automotive radar channel model must capture the physical locations of the radar, targets to detect and possible wave reflection and scattering objects. Thus, [JY19] proposes to study a hybrid of deterministic and stochastic model for radar evaluations. 2.2.2.3 Antenna modeling is a part of ...
