摘要：
The estimation and mitigation of swept-tone interferers includes receiving a composite signal comprising a signal of interest and a swept-tone interferer over an observation bandwidth or a hop bandwidth in a frequency -hopping system. The estimation of the interfering signal may be based on modeling the interferer as a magnitude periodic signal comprising non-overlapping, contiguous epochs, where each epoch may comprise a common pulse shape and a distinct phase rotation. The modeling may be based over the observation bandwidth, the hop bandwidth, or after combining the signal over all the frequency hop bandwidths. The period of the magnitude-periodic signal may be initially determined, and the common pulse shape and each of the distinct phase rotations may then be estimated. These estimates may be used to reconstruct an estimate of the swept-tone interferer, which may be subtracted from the composite signal to generate an interference-mitigated signal of interest.
摘要（中）：
扫频音干扰信号的估计和减轻包括在频率跳跃系统中的观测带宽或跳频带宽上接收包括感兴趣信号和扫频干扰信号的复合信号。 干扰信号的估计可以基于将干扰信号建模为包括非重叠邻接历元的幅度周期信号，其中每个历元可包括共同的脉冲形状和不同的相位旋转。 建模可以基于观测带宽，跳频带宽，或者在将信号组合在所有跳频带宽之后。 幅度周期性信号的周期可以初始确定，然后可以估计公共脉冲形状和每个不同的相位旋转。 这些估计值可以用于重构扫频干扰信号的估计值，该信号可以从复合信号中减去以产生一个干扰减轻的感兴趣信号。
