Remote air-to-air missile multi-platform cooperative guidance system and realization method thereof

Abstract: The invention discloses a remote air-to-air missile multi-platform cooperative guidance system and a realization method thereof. The multi-platform cooperative guidance system comprises an early warning plane module, a ground base radar detecting module, an aerial carrier module, a friend plane module, a remote air-to-air missile module, a target information space-time normalizing module and a target information fusion module. The realization method comprises the following steps: 1. an early warning plane, a ground base radar guided aerial carrier and a friend plane fly to a war area; 2. the radar of the friend plane operates to detect a target, and the aerial carrier launches an air-to-air missile; and 3. the targets detected by the radar of the early warning plane, the ground base radar and the radar of the friend plane are fused, and the friend plane carries out midcourse guide on the air-to-air missile. By adopting a multi-platform combat network formed by the early warning plane, the ground base radar, the aerial carrier and the friend plane to provide high-accuracy target information for the remote air-to-air missile, and adopting the friend plane to perform midcourse guide on the remote air-to-air missile, a remote target can be attacked stealthily and accurately.

Missile tracking using knowledge-based adaptive thresholding

Abstract: We apply a knowledge-based segmentation method developed for still and video images to the problem of tracking missiles and high speed projectiles. Since we are only interested in segmenting a portion of the missile (namely, the nose cone), we use our segmentation procedure as a method of adapting thresholding. The key idea is to utilize a priori knowledge about the objects present in the image, e.g. missile and background, introduced via Bayes' rule. Posterior probabilities obtained in this way are anisotropically smoothed, and the image segmentation is obtained via MAP classifications of the smoothed data. When segmenting sequences of images, the smoothed posterior probabilities of past frames are used as prior distributions in succeeding frames.

Test Mechanism for Measuring Pitch-Damping Derivatives of Missile Configurations at High Angles of Attack

Abstract: : Pitch-damping tests were conducted at M = 1.96 to evaluate the newly developed high-alpha missile test mechanism. Data were obtained using the small-amplitude free-oscillation technique at angles of attack from -12 to 86 deg at Reynolds numbers, based on model diameter, of 86,000 and 187,000. Two missile configurations having length-to-diameter ratios (l/d) of 10 and 15 were tested. The l/d = 10 configuration is commonly known as the Basic Finner. The test mechanism proved capable of measuring the pitch derivatives. Strut interference was not appreciable. The derivatives were found to be nonlinear functions of angle of attack, and previously published data at low angles of attack agreed well with the present results.
