Abstract: Synthetic aperture radar seeker can effectively improve the guidance accuracy of long-range missiles.The principle,analytical expressions and detailed flow of missile location using range-Doppler domain data provided by SAR seeker,missile velocity calculated by inertial navigation system and altitude measured by altimeter are described orderly.Based on simulation,the effects of digital image matching,altitude and velocity errors on the geo-location accuracy are compared.
