Description: 从回波中估计多普勒参数是合成孔径雷达运动补偿的关键。文中研究了多目标回波对参数估计的影响，从理论上推导了估计多普勒中心和调频率对回波的不同要求，并用两个指标举例分析了一段实测机载SAR数据，给出了实际应用中参数估计时选择回波的原则。-Doppler parameters estimation from radar echoes is a key step in SAR(Synthetic Aperture Radar}motion cornpensation．
This paper researched the efect of multiple targets echoes to estimate parameters and deducted theoretically the different
requirement for echoes in estimating doppler centroid and doppler frequency modulation rate．Th en giving a real airborne SAR echo
as example，we analyzed it with two measurements and concluded the principle about choosing echoes in practice．

Description: 使用维纳分布进行瞬时频率估计用来校正电离层非线性相位污染带来的频带展宽-High-frequency (HF) sky-wave radar
signals propagate to and from the target by means
of the ionosphere. The difficulty in obtaining very
narrow beamwidths at HF, and the long ranges
involved, mean that the signal backscattered from
the ground is often several orders of magnitude
greater than the target echo. To resolve the target,
coherent signal processing techniques are necessary,
detecting the target echo by virtue of the
Doppler shift caused by the target’s radial velocity.
Unfortunately, movement of the ionospheric
layer by which the radar signal has propagated
often causes the clutter spectrum and target to
spread in the frequency domain, rendering
extended coherent integration pointless. The
movement of the ionosphere can be regarded as
producing frequency modulation of the radar
signal, and thus if this modulation can be estimated
the radar signal may be corrected for the ionospheric
contamination. A technique using the
complex argument of the first-order mo

Description: Radar can determine an object’s location, keep a record of past locations, and can give an estimate as to where this object, or target, will be. Radar measures a target by emitting an electromagnetic signal and measuring the reflection off of the target. By measuring the round trip time and Doppler frequency shift, this method measures distance and velocity very well, but measures angle very poorly. Sometimes rather than keep track of every aspect of a target’s trajectory, radar will instead use a simplified representation based on only one or two observables that are measured very accurately and precisely – range and Doppler frequency shifts.
