Modulation Waveforms for Continuous Wave Radar,

Abstract

The range of a radar is a function of average transmitter power and is independent of the modulation waveform. It does not matter whether the transmitter operates in a pulsed or CW mode. In many applications, an average power of only a few watts is adequate. In these cases, CW operation can have a number of advantages. Solid state power sources can readily be utilized and a single RF source can serve as both transmitter and local oscillator. Another advantage is waveform flexibility. In a CW radar the waveform can be designed to perform a variety of functions, e.g., detect fixed and moving targets, determine sense of radial velocity and communicate with a target over a fade-free channel. This paper describes waveforms and design techniques that can be used to achieve the above mentioned functions with a CW radar. (Author)
