摘要： PURPOSE:To correct and eliminate optimumly a stripe-like noise on an image by calculating the statistic of an output image intensity at every image detector and obtaining an image intensity correcting quantity through a frequency space filter, etc. CONSTITUTION:An earth observation data in a satellite 1 is recorded in a high density magnetic tape 4 at a real time by a system 3. The uncorrected image data of the tape 4 is read by a device 6, stored in a disk device 9 and simultaneously, the statistic of every detector of the satellite 1 is calculated by an arithmetic unit 7. An arithmetic unit 10 calculates the estimation of a detector offset of the satellite 1 and an intensity correction of one picture element, executes Wiener filtering simultaneously, and an arithmetic unit 11 calculates a frequency filter. In this way the arithmetic unit 10 stores an image intensity correction coefficient in a storage device 14. Also, the j-th image data train is brought to an intensity correction by a correcting device 13 and recorded in a tape 5 through a control device 15.

摘要： PURPOSE:To obtain a reproducing image of high brightness by providing a restricting filter producing section for producing a shading rest-ricting filter based on a set height. CONSTITUTION:A receiving signal of a radar is outputted to a pulse compressing section 9 from a receiving signal fine 10. A parmeter setting section 13 sets a value of height H of an objective body and supplies to a shading restricting filter producing section 12. In the shading restricting film producing section 12, a shading restricting film is produced from a shading function and supplied to the pulse compressing section 9. In the pulse compressing section 9, a pulse compression is performed, and the compressed result is outputted to a reproducing image file 11. In this manner, a reproducing image of a high brightness is obtained in which a power of all receiving signals of a reflected wave from an observed target focuses on one point.

摘要： PURPOSE:To obtain a clear image to a distance direction circumferential section by all lookings by removing a major part of shading in a distance direction which may be generated in respective looks of a reproducing image and a distance direction circumferential section in a resampling processing of an azimuth compression. CONSTITUTION:A parameter precisely estimating section 6 analyzes a power spectrum and a phase of an azimuth direction of an output signal of a distance compression section 5 and thereby precisely estimates an error included in values of KD and fD in the output of a parameter roughly estimating section 3 and based on this result, corrects KD and fD and outputs. An azimuth compression section 9 execute Fourier transform the direction compressed output signal in the azimuth direction at first, and then, corrects a range migration distorsion included in said signal. Since thid distorsion is a geometric distorsion of the signal, in a distorsion correction, a resampling for quantizing the signal again is required. A signal in which a range curvature distorsion is corrected, similarly to the distance compression, obtains a multilication of azimuth compression reference function and a complex conjugate function, and thereafter is executed reversely Fourier transform to be an output signal of the azimuth compression and stored in a reproducing image file 10.
