WebThe ERS-1 radar sensor has a slant range pixel spacing of 7.9 m, nominal incidence angle of 23 degrees, and nominal range of 853 Km to the center of the image swath. For an 8 look image with a SNR of 20, the theoretical height resolution is better than 2.5 m for a wide range of correlation values y. 26. WebThis system simply measures the range at fixed intervals and computes the rate of change between the measurements. For example, if a target is at 1500 m for the first measurement and at 1492 m for the next measurement made 1 sec later, the range rate is -8 m/s.
