| Abstract: | Presumming of data prior to correlation is considered as a means for achieving the desired performance in a side-looking radar with a minimum amount of digital storage. A presummer with optimal resolution is derived for this purpose, and the optimal apportionment of the available storage capacity between the presumming and correlation operations is determined. The optimal presumming coefficients are given for the condition that the illumination pattern of the antenna illuminates uniformly a Doppler bandwidth equal to the PRF of the radar. The obtainable optimum resolution is given as a function of total storage and of the number of transmitted pulses in the received Doppler history. Expressions are also given for responses with presumming for linearly frequency-modulated signals and their matched filters. |

This collection of SAR literature is far from being complete.
It is rather a collection of papers which I store in my literature data base. Hence, the list of publications under PUBLICATIONS OF AUTHOR'S NAME
should NOT be mistaken for a complete bibliography of that author.
