摘　　要：采用四片ADSP-TS101S构成的雷达信号参数估计平台,实现了基于三次相位函数的多项式相位信号参数估计算法。该算法只需要通过二阶非线性变换即可实现PPS的参数估计。硬件实验表明,该算法可在低信噪比条件下准确地估计PPS参数,并且通过多片流水式的并行处理,最大限度地节省了估计时间。This paper used a platform to estimate the parameters of radar signals based on 4 ADSP-TS101Ss, which made the algorithm for estimating the parameters of polynomial phase signal（PPS） radar signals based on the cubic phase function come true. It just needs second-order nonlinear transform to estimate the PPS parameters. Hardware experiments show that the method is exact to estimate the PPS parameters in lower SNR, and saves estimating time mostly with pipeline parallel processing on multiple ADSPs.
