  target resolution
Model-based frequency estimation algorithms, developed during the last decades, can essentially improve target resolution and distance accuracy.
      
Moon's surface being a poor reflector, the choice of receiver size and its type and the selection of detector play an important role in getting a good signal-to-noise ratio and in turn achieving the target resolution.
      
Target resolution often gives a quite different impression of proprioceptive exactness than do measures of accuracy based on mean error.
      
We derive the equation for calculating target resolution and give example resolutions for several joints we have tested.

The target resolution of line scanners is analyzed quantitatively. It is concluded that its resolution greatly exceeds the limit of instantaneous field of view (IFOV). When the scale of the target or its internal radiance distribution is smaller than the IFOV, we can abtain a distorted, i.e., expanded and boundary blurred response. But if the contrast of target radiance distribution is large enough, this distribution can be imaged and distingushed. Particularly, for linear or spot targets,...

The target resolution of line scanners is analyzed quantitatively. It is concluded that its resolution greatly exceeds the limit of instantaneous field of view (IFOV). When the scale of the target or its internal radiance distribution is smaller than the IFOV, we can abtain a distorted, i.e., expanded and boundary blurred response. But if the contrast of target radiance distribution is large enough, this distribution can be imaged and distingushed. Particularly, for linear or spot targets, as long as the contrast or radiance increases by a factor of SL/ST, it can certainly meet the condition of any equations constructed for the distinguishable targets, here SL and ST expresses respectively the areas of the IFOV and the target. If we further make use of the difference of spectral characteristics between the target and background, we can improve the target resolution obviously.

本文定量地分析了行扫描仪的目标分辨能力。结果说明,其分辨能力大大超过了瞬时视场的限制。当目标或其内部亮度分布的线度小于瞬时视场的线度肘,我们能得到一种畸变了的,即被展宽而且边沿模糊了的响应。但是如果目标亮度分布的对比度足够大,这种分布就能被成象并被识别。特别是对线性甚至点目标,只要其对比度或亮度增加到S_L/S_T倍,就确定地能满足已建立的任何可识别的条件方程,这里S_L与S_T分别表示瞬时视场和目标的面积。如果进一步利用目标与背景间不同的波谱特性,还能明显地改进目标分辨能力。

A new hybrid waveform is designed by utilizing Costas TH and pulse compressing of complementary code sets. By means of analyzing constructions and ambiguty properties of the two different TH models of hybrid waveforms, it is shown that hybrid waveforms not only have simple constructions and are easy to processing, but also have properties of nearly ideal target resolution and strong capability of clutter depressing and good characteristics of ECCM.

Estimating the arrival time of overlapping echoes by high resolution array processing algorithms can efficiently expand the ability of target resolution in radar. Lowering the SNR threshold at which the algorithms take effect has particularly been an area of focus for practical applications. In this paper a novel method based on pulse compression for range super-resolution is presented. The proposed method, especially suitable to large time-bandwidth product (TB) signals, can be applied at very low SNR and greatly reduce the computational load in comparison with the known approaches.

利用高分辨阵列处理算法实现重叠回波时延超分辨是扩展雷达距离分辨率的有效方法,而降低这类算法适用的信噪比(SNR)门限是其能否实用的关键。本文针对大时宽带宽积(TB)信号压缩后能量集中,峰值SNR提高的特点,提出了一种低SNR下大TB信号距离超分辨新方法.即利用脉压和旁瓣抑制技术对大TB信号进行预处理,结合噪声的预白化,对截取的脉压输出主瓣进行超分辨处理。计算机模拟表明该方法可以在低SNR下实现多目标的距离超分辨估计,并大大降低数据存储量和计算量.
