Abstract:
Airborne imaging radar systems are known by their ability to produce high
resolution images of ground targets using microwave region of electromagnetic
waves. There are many military and civilian applications of imaging radar
systems. The high resolution images achieved by transmitting a number of
electromagnetic pulses to the earth surface then integrating them coherently at the
receiver. A study have been achieved to show the effect of changing speed or
height or both of the airplane carrying the focused synthetic aperture radar upon
the azimuth resolution. The simulation results showed that increasing the speed or
decreasing the height of the airplane will improve the azimuth resolution, and it
can be noted for practical parameters that decreasing the speed and the height of
the airplane leads to degraded azimuth resolution. The results of azimuth
resolution obtained from simulations and those from theoretical calculations are
nearly identical for targets of point reflecto
