摘要： PURPOSE:To attain the data ciphering with high reliability by providing a means operating random number data generated from a random number generator and input data. CONSTITUTION:Keys K1, K2 are inputted externally prior to the ciphering and stored in key registers 1, 2. Random number generators 3,4 generate a pseudo random number series one after another by,e.g., the congruence method according to the content of the registers 1, 2. The input data is applied with operation (g) to a random number data generated by the generator 4 and stored in order from the head of an input data buffer 5. After 256set of data are stored in the buffer 5, an address generator 6 inputs the output data just before being stored in a delay device 7 and the result of operation (f) applied to the random number data generated from the generator 3 and outputs an address in the buffer 5 for the data to be outputted.

摘要： PURPOSE: To attain to enhance the image quality of a regeneration image, by dividing image pickup data in an azimuth direction and performing the estimation of a regeneration parameter at every divided part.
CONSTITUTION: A bearing 22 is taken horizontally and a range direction 23 is taken vertically and image pickup data are divided, for example, into four parts. N shows the size (picture element unit) of a divided unit in the bearing and an exponent value of 2 is selected from relation using high speed Fourier transformation. Next, M has a size allowing adjacent divided parts to overlap to each other and, when the size of a spot image in the bearing is set to L, M≥L/4 (in the case of multilook number = 4) must be formed. Subsequently, because the divided parts of picture elements 31, 32 regenerated from lefthand and righthand divided parts are regenerated using different regeneration parameters, the picture elements 31, 32 are shifted in a phase and, in the interpolation at a part A, interpolation can be performed using only the picture element and, in the interpolation at a part B, interpolation can be performed using only the picture element 32. Therefore, it is prevented that the interpolation is performed using both of the picture elements 31, 32 and the quality of a regeneration image can be enhanced.

摘要： PURPOSE:To attain image quality evaluation close to human's visual evaluation by comparing the original shape of an object with the shape on an image. CONSTITUTION:In one area of an image, the original shape of the object is compared with the shape of the image. For instance, a shape having a certain angle is quantified to indicate the degree of practical clearness of the angle and the quantified value is used as a picture quality evaluation value. For instance, a part to be estimated as a right angle from an image is extracted. In this case, the part may be extracted as a binary-coded number or a line. Then, a circle is fitted to the extracted angular part to find out the radius R. Generally, a right angle is deformed in accordance with the increase of R. Therefore, the picture quality can be evaluated by comparing the R.

摘要： PURPOSE:To eliminate a blur contained in a sample signal and whose size is varied as the time passes, by providing a blur eliminating interpolation weight function whose blur elimination quantity is a parameter, on an interpolation weight function table, and using it as a three-dimensional number table. CONSTITUTION:An input signal file 1 stores a receiving signal. A geometrical strain supply part 15 derives a sample position on an input sample signal with regard to a designated sample of an output sample signal. On the other hand, a blur elimination quantity converting part 17 derives a blur quantity in a coordinate which has been given. An interpolation weight function switching part 8 switches the contents of an interpolation weight function table 16 in accordance with an output of the converting part 17. An interpolation processing part 19 executes simultaneously a correction of a geometrical strain and an elimination of a blue by executing an operation. In this regard,the input sample signal is a sample signal of a one-dimensional signal in a frequency of a receiving signal. The output sample signal is stored in an output signal file. According to this constitution, an interpolation can be executed by switching a blur eliminating interpolation weight function to an optimum one at every sample.

摘要： PURPOSE:To discriminate a feature area with high accuracy by setting minor areas with small spaces secured among them so that an overlapped part is produced between minor areas and discriminating the feature area for each small area. CONSTITUTION:The feature quantity is calculated for the 1st minor area 21 of (mXm) picture elements in a picture 20. This feature quantity is compared with the prescribed threshold value to decide that the area 21 is equal to a feature area. Then the point '1' is added to each picture element in the minor area. While the point '-1' is added to those picture element if no feature area is decided. Then a minor area 22 is set with a right shift by a picture element, and the decision is carried out in the same way for a feature area. Such an operation is repeated up to the final minor area 27. Then the points are totalized for each picture element. A feature area is defined with the picture elements having the totalized point larger than zero; while no feature area is defined with picture elements having the totalized point smaller than zero respectively.

摘要： PURPOSE:To minimize blurring of a reproduced image not only in the central area thereof but also in the peripheral area, by generating a reception signal or a range compressed output signal from an original reception signal or the range- compressed output signal. CONSTITUTION:A reception signal in the skew coordinates system is range-compressed with a range compression section 44 and the results are memorized. Acceleration Av is calculated from a skew coefficient calculated with a skew coefficient calculating section 42, a telemetry data and the like. Then, the range- compressed output signal is resampled in the azimuth way using an acceleration data obtained from an acceleration resampling section 46 to generate a range- compressed output signal of a received signal when a flying object flies in acceleration. This can keep the azimuth FM ratio K and the range curvature constant in a spot image pattern at the reflection point of a microwave in the skew axis thereby minimizing the blurring of a reproduced image.
