 | The lack of a utilitarian solution to the frame-to-frame correlation problem poses insurmountable difficulties for the successful passive observation of a collection of co-moving, nearly co-located objects. This is exactly the task faced in a scenario with respect to intercontinental ballistic missiles of the multiple re-entry vehicle delivery type. This report presents the conceptual framework for a potentially viable correlation algorithm. As well, the formal mathematical explication of the technique ... |

|
| This Project Report discusses an attempt to calibrate photometric data acquired from streaks generated by moving objects which were observed at the ETS. This is desirable for both natural and artificial bodies. The utility of a meaningful apparent magnitude from streak data would allow statistical studies of size-albedo distributions, serve as a size indicator in the absence of traditional photometry, and alleviate the difficulties of artificial satellite photometry on the ... |

|
| Over the past few years, passive, ground-based, angles-only initial orbit determination has hd a thorough analytical, numerical, experimental, and creative re-examination. This report presents the numerical culmination of this effort and contains specific recommendations for which of several techniques one should use on the different subsets of high altitude artificial satellites and minor planets.

|
| Specific application is made to searches for near-stationary artificial satellites and to the classical along orbit search. These two reflect different limiting cases for the a priori target distribution (uniform for the near-stationary case) and the conditional detection probability (uniform for the along orbit case). Our treatment of the near-stationary case is as realistic as is currently possible. Atmospheric extinction, eclipses, and phase effects are all included. Similarly we have ... |

| Optimal Search Theory and Optical Artificial Satellite Searches |

|
| This report discusses the along orbit search, by optical means, for an artificial satellite. In particular the attempt is made to couch the search in the existing scenario of optimal search theory. This cannot be done for existing and envisaged searches. The reasons for this are explored and some new concepts of optimality are discussed for real searches. The point is made that both hardware and software adjustments would be ... |
