Power Efficiency of High Dynamic Range Noise Waveform
Janusz Kulpa , Anna Kurowska
AbstractNoise radars - radars that use random waveforms as sounding waveforms - are prone to what is known as a masking effect. This occurs when the correlation sidelobes of a strong target echo masks weaker echoes. In order to overcome this limitation, the sounding signals which have correlation functions with suppressed sidelobes may be used. When designing such signals, the power efficiency should be considered, which is increased by decreasing the peak to average power ratio of the waveform. In this paper filter-based waveform design methods are pre- sented and discussed. Three different approaches are analyzed that modify filter-based sidelobe suppression algorithms in order to achieve good power efficiency of the output waveform. Both simulation and measurement results are shown presenting, the benefits of the proposed methods.
