Abstract

As there is a restriction in coding length selection when using the original phase-encoded and frequency-hopped signals to compose a single-cycle FSK/PSK signal, a new method for generation of a multi-cycle FSK/PSK signal is proposed which allowed selecting the coding sequences of all length. The ambiguity function expression of this type of signal is derived. The distance and speed resolution has been analyzed and simulated. The LPI performance is also been analyzed theoretically in this paper. The result shows that this type of signal has an ambiguity function close to the ideal “thumbtack” ambiguity function and has a good performance on distance and velocity resolution, and the LPI performance is significantly improved.
