Because of its simple and mature technique,two-phase code signals become the common pulse-compress radar signals.

In this paper,a new wavelet basis function is constructed,and a new method of detecting two-phase code signal based on continuous wavelet transform(CWT) is provided,and the simulation test of two-phase code signal mixed with Gauss white noise has been performed.

An algorithm of estimating carrier frequency,symbol rate and phase-coded sequence of binary phase-coded signals;

The parameters estimation of multiple simultaneous binary phase-coded signals is the key problem in the filed of radar and communication countermeasure etc.

A Doppler compensation method for biphase coded signal based DMTD is presented and realized.

By the study of Taylor four-phase coding signal,its advantages and shortages are analyzed.

The analysis of intra-pulse features of baseband phase-coded signals at lower SNR;

But the application area is restricted because phase-coded signal is Doppler sensitive.

This paper analyzes discontinuous spectra radar signal system,proposing a intra-pulse phase modulation and inter-pulses frequency hopping signal which combines phase-coded signals and frequency-hopping signals.

Introducing the sidelobe suppression of the LFM signal and phase coded signal depending on windowing weighted,the paper also gives the correspondent simulations and compares their results.

This paper analyzes the binary-phase and multi-phase coded radar signals,applies the cumulant of complex envelope and matrix theory to process the phase coded signals,puts forward a new recognition method of phase coded signal,deeply discusses the method combining with the computer simulation,educes the conclusion that this method is provided with certain applicability.

There are two difficulties when applying the channelized receiver to intercept a broadband phase coded signal (PCS).
