Abstract

The Iridium L band downlink signals from a radar viewpoint are studied. The signal is modelled and its ambiguity function is analysed and the ambiguity function with that of the real recorded signal is compared. It is shown that the spectrum and ambiguity diagram of the Iridium signal are independent of the signal content, making it a very suitable signal of opportunity for passive radar. The interference floor of the ambiguity function of a single Iridium burst with a length of 8.28 ms is about 22 dB lower than the main peak.
