Abstract

Software radar technology allows use of probe signals with nonrectangular envelope. Even simple waveforms can achieve much better performance than traditional square pulse. Pulse with optimal trapezoidal envelope introduced in current article has higher spectral efficiency, lower Doppler side lobes and better range resolution than square pulse with same duration. Probe signals with variable envelope sets higher demands to linearity of power amplifier. Linearization techniques are discussed and digital predistortion method is found to be most suitable solution for software radar. Possible uses of probe signals with nonrectangular envelope are discussed.
