Title: Method for controlling the flight of rockets

Abstract: FIELD: military equipment.  
     SUBSTANCE: invention relates to the field of military equipment and can be used to aim rockets at a target to destroy military equipment and enemy manpower. The method involves control of the flight of rockets using a launcher with guide frames. A radar station is provided, with the help of which the coordinates of the trajectory of rockets are determined. The direction of their movement, coordinates and movement of moving targets are tracked. Rockets have devices for trajectory correction, radio receivers for receiving a radio signal from a radio transmitter, a counter for choosing the trajectory correction blades. To increase the reliability of the information transmitted to the missile, the projectiles are fired in small packs of four to reduce the duration of the transmission cycle of information to the rockets in the air. This is facilitated by the starting signal, transmitted simultaneously to all missiles, the duration of which corresponds to the flight time of the first projectile to the middle of the trajectory. After that, the trajectories of each projectile are corrected. Before the start, information about the coordinates of the targets for each of the shells is entered into the computer. From the same moment, radar tracking of the coordinates of moving targets begins. Correction of trajectories of projectiles in the horizontal and vertical planes is carried out by means of radio pulses with the direction of correction depending on the time of the pulse transmission and the angle of correction depending on the duration of the radio pulse. Correction of the trajectories of missiles is carried out cyclically and alternately for each of the projectiles until the end of the flight. Correction in the horizontal plane is carried out with the left and right blades, correction in the vertical plane - with the upper and lower blades. 
     EFFECT: increased accuracy and a shot grouping.

Abstract: FIELD: instrument engineering.  
     SUBSTANCE: invention relates to the field of instrument engineering. The method for combined calibration of the accelerometer block consists in the fact that a single array of residuals of the received and expected measurements of the apparent acceleration vector and its absolute value is formed from the obtained measurements. The resulting array is linearly associated with the calibrated parameters of the accelerometer error model. The influence of residuals in individual measurements and in the absolute value of the acceleration vector on the obtained estimate is balanced by setting the Kalman filter algorithm for a stationary system, with the help of which the correction vector of the parameters of the measuring model of accelerometers is estimated, that is, their refinement.  
     EFFECT: increase in the accuracy of calibration of the accelerometer block.

To this end, for the current coordinate value on the time axis of the short-time Fourier transform (STFT) matrix, root-mean-square deviations of its frequency values are calculated. Tripled value of the calculated root-mean-square deviations of the frequency values is then compared with the maximum STFT values for the current coordinate value on the time axis, which are called the current maximum value. Assigning a unit value to all matrix values for the current coordinate value on the time axis, if its current maximum value exceeds triple value of its root-mean-square deviations calculated for the current coordinate value on the time axis. Zero value is assigned to all values of the matrix for the current value of the coordinate on the time axis, if its current maximum value does not exceed three times the value of its root-mean-square deviation.EFFECT: enabling demodulation of ASK signals under conditions of fading in a receiving channel by normalizing values of the STFT matrix independently for each current coordinate value on the time axis relative to its current maximum value.1 cl, 4 dwg

Abstract: A method and a circuit arrangement for modifying central control information commands forming signal programs in traffic signal systems in particular street traffic signal systems, the central control information commands being output from a central station to intersection devices of the system in order to control signal generators assigned to the intersection devices. This modification is to occur through the use of traffic information which are determined in the traffic areas whose traffic flows are to be controlled by the signal generators of the intersection devices. In order to be able to undertake a modification of the signal program sequencing in the respective intersection devices, modification time areas are determined in the form of partially overlapping central control information commands, in particular binary "1's" transmitted from the central station to the respective intersection device. Within these modification time areas, separate local control information commands can become effective for setting the signal generators.
