Parameter estimation in detection of BPSK radar signals

In process of detecting low probability of intercept radar signals, cyclostationary spectral can be adopted in the method to analyze and detect BPSK radar signals, the carrier frequency and code-width etc parameters as a result can be detected and estimated in comparative low signal-to-noise ratio environment. In the environment that signal-to-noise ratio turns further lower, cyclostationary spectral can be combined with cepstrum as methods to be taken in identifying BPSK radar signals and estimating key parameters like carrier frequency and code-width.
