1993
This chapter deals with Doppler techniques and their different applications for surveillance radar, multifunction radar and synthetic aperture radar. The chapter presents: an analysis of a simple pulse Doppler radar [fixed station, low pulse repetition frequency (PRF), no range ambiguity] (radar characteristics, power and spectra of clutter and target,

Doppler shift for a radar echo
American Journal of Physics, 1979The Doppler shift formula for a radar echo is derived without the use of transformation equations by considering the superposition of the incident and reflected waves. The results are then used as a basis for a discussion of the concepts of proper length and time as regards the transformation properties of wavelength and period in special relativity.

Doppler Radar Measurements of Turbulence
2016A first-principle analysis of Doppler radar measurements of turbulence is presented. A set of limited, though practical, conditions are assumed to make the problem more tractable, with the primary condition being the discrete and finite temporal sampling of the radar signals.

History of Doppler Radar Navigation
Navigation, 1993This paper traces the history of the development and applications of Doppler radar navigation systems from their inception in the mid-1940s to the present. The early design concepts, problems, tribulations, and obstacles are discussed. With only noncoherent pulse radar transmitters available at that time, a unique technique of self-coherence had to be ...

Doppler Radar Observations of Mammatus
Monthly Weather Review, 1995Abstract Observations of mammatus-like cloud features associated with a convective rain shower were obtained using a vertically pointing 8-mm-wavelength Doppler radar. The radar's excellent sensitivity and resolution allowed even very weak, finescale features of the cloud to be resolved.

1987
Relative motion between a signal source and a receiver creates a Doppler shift of the source frequency. Likewise, when a radar system illuminates a moving target that has a radial velocity component relative to the radar, the signal reflected from the target and received by the radar is also frequency shifted.
