For deficiencies of existing design methods of orthogonal coded signals such as notably computational
complexity, limited coding length and limited signal number, a kind of random discrete frequency coding signal
based on chaotic series is proposed in this paper, considering the attracting characteristics of chaotic series such as
noise like behavior, initial value sensitiveness and easy for generation and use. The time-Doppler ambiguity
function of the designed signal is induced in detail, the range and Doppler resolution are analyzed, and the
pseudo-orthogonal property is discussed in this paper based on the signal coding model. Signal performances are
compared with different chaotic series. The proposed signals present quite good performances in ambiguity
function, pseudo-orthogonal property, easy generation and unlimited coding length and large signals’ number, and
can be applied as a kind of promising radar signals.
