AbstractInitial evaluation of the JERS-1 SAR has been conducted for its characterization using inflight calibration signal, raw data from the natural targets, such as urban, mountain, forest, and ocean areas, and some correlated images for the antenna elevation pattern determination as well as the ground based measurement for its azimuth pattern. Calibration signal was used to obtain the suitable reference function for the range correlation more than ground measurement. Natural targets' signals were used to evaluate the raw data quality as well as the targets' characterization. As a result, most of the SAR characterization was conducted and recognized as same as designed except that the saturation and bit redundancy errors of several percent due to 3 bit AD converter underestimates the received power by 0.45 dB as an averaged value and chirp rate was measured lower than pre launch data by 0.3%.
