On the Eclipsing Phenomenon with Phase Codes

This paper is interested in phase code design, and especially in their robustness to the eclipsing phenomenon. In a radar background, the term "eclipse" describes a partial loss of data at the reception side. It implies an increase of pulse compression sidelobes, and thus a degradation of detection performance. In this regard, this paper describes an optimisation procedure which aims to provide waveforms (phase codes) that are quite robust to the eclipsing phenomenon. Some simulations are provided to highlight the usefulness of the procedure.
