This paper gives a data-processing method to improve the detection ability of warming radar-A retrospective correlation method.

There are three adaptive ways:pilot signal,minimizing the measured power signal and relativity of the measured power signal.

In this topic,the specific scheme,used for the characteristics of the output signal on all-fiber-optical current transducer, using the correlated detection algorithm to extract the noise drowned by the weak signal.

The research of digital correlation detection experiment based on GPIB interface;

An automatic measurement system for extinction ratio in visible spectrum based on correlation detection principle;

Study on correlative detection of LFM pulse compression signal with polarization agility;

The detection theory of resonator fiber optic gyro(R-FOG) based on the serrodyne modulation with two frequencies was introduced,and the correlative detection theory in digital system was analyzed.

Using the excellent correlation property of m-sequence, correlative detection and accumulation algorithms, this method can effectively improve the performance of the laser radar.
