摘　　要：介绍了全去斜率脉压处理的基本原理。测试系统采用全去斜率接收处理技术,使运算量大大减少。量化分析了采用海明加权对一维距离分辨率的影响。最后结合雷达外场动态测量,实现了对海上船只的一维成像。With the basic principle of the fully de-chirping processing introduced,the stretch processing technology is adopted to greatly decrease the amount of calculation for the test system.Besides,the effects of the Hamming weighting on the 1D range resolution are quantified and analyzed.Finally,combined with radar field dynamic measurement,the range profile of ships is implemented.
