The processor uses the characteristic that the noncoherent integration of independent and identically distributed noise is very similar to a Gaussian distribution to obtain the mean and covariance estimaties of the integrated noise from adjacent range cells.

First,non-coherent integration is used to reduce false alarms,and then,a two-level plot clotting method based on CPI is presented.

Effective coherent integration algorithm for high-speedmoving targets in Chirp radar;

The simulation results show that the performance of the method based on Keystone transform is better than that of the classical coherent integration method.

How to detect moving target in low SNR condition for moving-baselines time difference measuring system is studied,using multi-pulses coherent integration algorithm.

Study on coherent accumulation against interference between radars with same frequency;

Then,the effect of improving UWB radar target recognition probability by echo coherent accumulation is analyzed.

This paper presents the function of OCXO s frequency shift according to the curve of frequency shift,and analyses the influence on PD radar s coherent accumulation and target speed test,and provides the limits of frequency shift.
