Analysis of Integrated Speckle Receiving Characteristics Based on Synthetic Aperture Imaging Ladar

Speckle reduction of synthetic aperture imaging ladar based on wavelength characteristics

“…According to Eqs. ( 12) and ( 13), the average image intensity of the ideal image is 5.5610×10 8 , and the value of the contrast is 1.2610×10 9 .…”

“…Thus, the complex amplitude of the integrated speckle field over the receiving antenna aperture can be obtained as [9] S (x r , y r ; t f , nT s ) = e speckle (x r , y r ; t f , nT s ) * A(x r , y r ; nT s )dx r dy r , (4) which is a 2D distributed optical field related to the fast time t f in the range direction and the slow time nT s in the azimuth direction. The * denotes a convolution.…”
