Abstract: The detection for echo of pulse radar demands a definite ratio of signal to noise.The analytic result shows that synchronous integration can effectively improve the Signal to Noise Ratio(SNR) of the pulse echo.This paper gives result for pulse integrated simulation,presents a synchronous integrator for pulse radar based on FPGA.The test result shows that this synchronous integrator can reach the system design request for improving the quality of radar echo.It is also easy to realize.So it is very useful in project design.

Key words: pulse radar, detection performance, synchronous integrator, Field Programmable Gate Array(FPGA)
