“…These criteria allow the evaluation of detection range at the radar system level. Besides, a high PMEPR may reduce the average transmitted power [6] thus reducing the detection range. At the ADC level, the maximum input power determines the maximum SNR after digitization.…”

This chapter proposes and tests an approach for an unbiased study of radar waveforms' performances. Through an empirical performance analysis, the performances of Chirp and Multitones are compared with both simulations and measurements. An ultra wideband software defined radar prototype was designed and the prototype has performances comparable to the state of the art in software defined radar. The study looks at peak-to-mean-envelope power ratio, spectrum efficiency, and pulse compression as independent waveform criteria. The experimental results are consistent with the simulations. The study shows that a minimum of 10 bits resolution for the AD/DA converters is required to obtain near-optimum performances.

In this study, we apply a protocol for an unbiased analysis of radar signals' performances. Using an experimental UWB software-defined radar, range profile, Doppler profile and detection range are evaluated for both Liner Frequency Modulated pulse and Multitones. The radar was prototyped and is comparable in overall performance to software defined radar test-beds found in the literature. The measured performances are in agreement with the simulations.

Abstract-In this study, a protocol for an unbiased analysis of radar signals' performance. Using a novel UWB softwaredefined radar, range profile, Doppler profile and detection range are evaluated for both Linear Frequency Modulated pulse and Multitones. The radar was prototyped and is comparable in overall performance to software defined radar test-beds found in the literature. The measured performance was in agreement with the simulations.
