The Selection of Signals for Continuous Wave Radar which Reduce the Sensitivity to Doppler Shift of Frequencies
Journal Title: TransNav, the International Journal on Marine Navigation and Safety of Sea Transportation - Year 2016, Vol 10, Issue 1
Abstract
The signals with ideal correlation properties are of interest for continuous wave radar. At the same time it’s important to provide low sensitivity to Doppler shifts of frequencies. There were considered signals with special structure due to amplitude modulation which provide capability of radar work with Search and Rescue Transponder (SART). Because the amplitude modulation has a drawback – not efficient use of signal energy, in a class of proposed signals there were considered signals with uniform amplitude. The mismatched filtering may be used by means special weighting functions for obtaining the necessary correlation properties.
