    摘要: For automated visual range measurement by a LIDAR system, a distance measuring range is first determined through repeated evaluation of a voltage level U(R) which indicates the intensity of a threshold value. After random initialization of a start value, the start value is then replaced each time with a new mean visual range, resulting in iterative improvements, and the mean visual range in the determined range is then displayed automatically as soon as the visual range lies within the measuring range of the LIDAR system. Using the Klett method, the accuracy can be determined with the aid of a breaking-off criterion in the form of a threshold value with respect to a deviation percentage between a new and a previous calculation. With this method the deviation can be identified to an order of magnitude of about 10%.

    摘要: For less expensive estimation the impulse response x.sub.MOS of a high-resolution, band-limited radar channel in a radar station operating with an expanded transmitted pulse a(t), from a received signal e, over which a correlated or uncorrelated additive interference signal n can be superimposed, with the use of knowledge about the spread code c and the use of a channel estimator with which a so-called linear, optimum unbiased estimation of the radar channel impulse response x.sub.MOS is performed in a time range covering M range gates of interest, the linear, optimum estimation in the unbiased channel estimator is modified in such a way that the pulse response x.sub.MOS of the band-limited radar channel is determined according to the basic principle of a multiplication of the sampled received signal e and an inverse estimation matrix A.sub.E.sup.-1. The matrix A.sub.E is formed by the extension of the rectangular matrix represented by the components c.sub.i of the spread code c to form a quadratic matrix that circulates to the right, that is, the modified, optimum unbiased estimation: x.sub.MOS =A.sub.E.sup.-1 e applies for a radar channel.

    摘要: In connection with a method for image generation by means of two-dimensional data processing, received SAR data are multiplied by a phase correction (H.sub.mc) for a reference range (r.sub.ref) for the insertion of a motion compensation and for processing at a high drift angle, and an additional cubic phase term is inserted for compensating a range migration. The entire range migration is then eliminated by means of an additional linear frequency displacement; subsequently the SAR data are transformed back into the "range-Doppler" domain. A remaining phase error, created by a "chirp scaling" correction, is corrected, the SAR data are transformed back into the time domain and a phase correction as a function of the range is performed by multiplication for the exact motion compensation in the time domain. The one-dimensional reference function is performed in the frequency domain for azimuth compression, by means of which two-dimensional SAR data are obtained.

    摘要: In a method for the detection, localization and velocity determination of moving targets from raw radar data from a coherent, single- or multi-channel image system (SAR), for representing the surface of the earth with different backscatter ratios, chronologically successive azimuth spectra are continuously formed during a defined period of time and a frequency shift of the backscatter ratio portion is obtained by determining the position of the maximum of the correlations between respectively two azimuth spectra formed chronologically directly in succession. Then the frequency shifts of the entire raw radar data set are evaluated for producing a frequency shift map.By searching for values deviating from the nominal Doppler rate in the Doppler rate map, a respective moving target is detected and the center of an image of the detected moving target is formed from this.By neglecting its radial acceleration, the tangential velocity of the moving target is determined by means of a Doppler rate taken from the Doppler rate map, and finally the radial velocity of the moving target is determined from the ratio of a length of the moving target in the range direction on the Doppler rate map and the duration of a scanning time by the antenna.

    摘要: A steering system for a road vehicle with front-wheel steering employs microprocessor integrating feedback of the vehicle yaw rate to the front-wheel steering actuator so as to decouple the yaw movement from the lateral movement of the front axle. Sensors measure vehicle speed, yaw rate (by gyroscope), lateral front axle acceleration (by acceleromether at the front axle), and the angle at which the driver holds the steering wheel. The microprocessor controls the front steering actuator according to a formula whose dependent quantities include the sensor outputs, fixed vehicle parameters (such as wheel base), and a preselected time constant. The vehicle's handling changes when the time constant is varied.
