Acoustooptic spectrum analysis of radar signals using an integrating photodetector array
Abstract
This paper examines the instantaneous Fourier power spectrum for different types of radar signals such as CW, pulse-modulated CW, and linear FM signals using an acoustooptic spectrum analyzer. The effects on the time-integrated output intensity distribution, due to the truncation of the propagating acoustic signal by the finite aperture width of the Bragg cell and the amplitude weighting on the signal, are also analyzed. Some experimental results on pulse-modulated CW and linear FM signals are presented and then compared to theory.
