WebThis paper proposes a new idea to design a waveform sequence starting from a reduced number of distinct cyclically shifted chirps by exploiting the Eulerian circuit. For a given number of distinct waveforms, the set of optimum shifts of the cyclically shifted chirps are provided as normalized values that can be used for any pulse width. WebThis paper considers chirp radar systems which time gate the passively generated pulses and presents the derivation of the hitherto unknown receiver response and a technique for the evaluation of a filter which will achieve range sidelobe suppression. 3 II. curly cow
