Its tracking pointing error is reduced to ±1.65° by theoretical analysis and ±3.4° by experimental verification. The requirement for tracking pointing precision which is within ±6° is satisfied.

The obtained star maps are identified using the calibration result. It is indicated that optical axis directional error is 4.846 2″,which shows the calibration result is more perfect.

The directional error of the three-axis flight platform-one of the factors affecting the aiming error is discussed, and the distribution method of three factors affecting the directional error is also presented.

The time-domain/frequency-domain correlation algorithm is used to carry out azimuth compression, and relationship of multi-look processing sub-image is used to estimate the deviations of Doppler central frequency and Doppler frequency rate caused from antenna direction error or SAR moving distable and to perform image restoring.

A combined guidance concept incoporating passive radar homing with strapdown inertial guid ance is selected to work against radar cutoff for anti-radiation missile,the extended Kalman filter method is used to correct direction error of inertial axis.

In this paper, a generalized kalman filtering method is used on an air to ground antiradar missile to slove the correction problem for the basic axis direction error of inertial terminal gnidance.

In this paper,a method of passive radar-homing guidance combinedstrap—clown inertial guidance is used on an antiradiation missile to work againstradar stopping radiating. The direction error of inertial axis is corrected by an ex-tended kalman filter.

Simulations under a few scenarios in the presence of steering error, array geometry error and sensor phase error demonstrate that this algorithm has excellent robust performance.

Some interaction between eye and head eccentricity also contributed to the pointing error.

The intensity distribution in a Gaussian beam is represented by a bundle of rays in which each ray has a random pointing error.

Without VS 73% of the volunteers showed a systematic horizontal pointing error towards the right side.

Consequently, the OP maneuver has a large pointing error.

The root mean square of pointing error of moving cable car was measured and the displacements of cable car within the wind speed of 8 m/s, which is the maximal wind speed of the place where the FAST will be located, were evaluated.

The neglect patients, unlike right brain-damaged patients without neglect, strongly reduced their rightward directional error in the supine compared with the upright position.

A systematic directional error was observed at the initial portion of the trajectory.

As the trajectory evolved, a different directional error emerged, resulting from a clustering of movement directions in two orthogonal axes.

This pattern of directional error increased in amplitude as the delay increased, in contrast to the error at the initial portion of the trajectory which remained invariant with increasing delay.

The constant directional error varied with target direction in a systematic fashion reproducing previous results and suggesting the same systematic distortion of the representation of direction in different memory delay tasks.

By the criteria of direction error and amplitude error the minimum latency for visually guided saccades is 110-130 ms for three subjects and 160 ms for a longer latency subject.

Developmental fractionation and differential discrimination of the anti-saccadic direction error

Furthermore, multiple regression analysis showed that the direction of the ideal saccade contributed significantly to the endpoint direction error, not the direction of the hand path.

Biophysics,21, 299-308, 1959) are generalized by considering that the angular direction error made by the driver, as well as the driver's reaction time are not constant but are randomly distributed.

BMD values of Chinese men in Taiwan, displayed by one-direction error bar.

A method of yielding phase disturbance on the phased array antenna to make the phase quantization errors shift circularly across the aperture was proposed. It can smooth out significatly beam pointing deviation arising from the quantization errors of digital phase shifters. Some optimistic results were obtained from a theoretical analysis and simulation test. The data show that the beam pointing deviation may in general be reduced in an order of two, and may be reduced at least in the order of one for 2-bit...

In this paper, data of the total flux observations of the sun at λ 3.2cm obtained in the Nanjing Univ. Department of Astronomy (N. U. A) during the years 1980—1981 have been analysed. Correlation analysis of the N. U. A. records as against TYKW(Toyokawa Obs., Nagoya Univ., Toyokawa, Japan) shows that in the course of one month, the relative residual standard deviation difference between the daily flux values amounts to ±1.06％- ±3.03％, giving a mean value ±1.867％. The accuracy of observed values is stable. The...

The accuracy of observed values is stable. The anologous results have been obtained from the error analysis. The mean ratio of solar flux densities between NUA9375 and TYKW9400 is linearly correlated with mean end temperature during a month. This indicates that observation values have a seasonal variation. Annual variation of the ratio is caused by the annual variation of back ground radiation, gain of the parabolaid antenna and atmospheric obsorption. The corrections to the antenna temperature caused by the absorption in a dark or awet day, pointing errors and gain shift have been obtained from the measurements and data analyses. They have been applied to the observed values. Comparing with the TYKW, One find that all the major bursts have been recorded with peak time deviation of ±0.15 min., and rms of relative peak intensity of ±20％.
