Description: ADXL362是一款超低功耗、3轴MEMS加速度计，输出数据
速率为100 Hz 时功耗低于2 μA ，在运动触发唤醒模式下功耗
为270 nA 。与使用周期采样来实现低功耗的加速度计不同，
ADXL362没有通过欠采样混叠输入信号；它采用全数据速
率对传感器的整个带宽进行采样(The ADXL362 is an ultra-low power, 3 axis MEMS accelerometer with output data
When the speed is 100 Hz, the power consumption is less than 2 A, and the power dissipation in the motion triggered wake-up mode
For 270 nA. Unlike using periodic sampling to achieve low power dissipation, accelerometers are different,
ADXL362 does not aliasing input signals via undersampling; it uses full data speed
The rate is sampled across the entire bandwidth of the sensor)

Description: In the proposed algorithm,
the range-independent de-rotation operation is employed to overcome the spectrum aliasing problem,
and the signal properties after de-rotation are derived in detail. Moreover, a modified range-dependent
deramp function is proposed to accommodate the time shift, and the chirp-z transform is utilized
for correcting geometry distortions caused by the range-dependent deramp operation. Furthermore,
range scaling and azimuth scaling are performed, providing the same pixel sampling interval for all
sub-swath images in both range and azimuth dimensions respectively, which avoids interpolation for
the sub-swath image
