    This paper is concerned with the accuracy of singlehit angle estimation by a monopulse radar in the search mode. The system analyzed is an amplitude comparison estimator. Off-axis targets are considered. The effects of narrow-band Gaussian receiver noise on the sum and difference signals are considered. An asymptotic expansion for the angle estimate is derived which converges for SNR's of 12 db or... View full abstract»

    A general method for identifying and evaluating magnetic sources associated with the magnetic airborne detector-equipped aircraft is described. It is derived for the compensation of magnetic noise related to the maneuvers of the aircraft. Mathematical formulas are included with a uniform engineering method, that is independent of the type of magnetic source encountered, for analyzing magnetic airb... View full abstract»

    Trans World Airlines will pioneer use of Doppler radar as a primary means of transport aircraft navigation over the North Atlantic. This paper summarizes flight test results using dual Doppler radar sensors and dual Doppler navigation computers on Boeing 707 long range aircraft. Test flights have been flown over TWA's North Atlantic routes for almost two years to "prove-in" the Doppler system. View full abstract»

    A long-range investigation into the transmission, utilization, and processing of information for missiles and space vehicles has been initiated. The ultimate objective is a theory of control and communication for such vehicles which would relate the principles of information theory to the design philosophy of the control and communication systems. In investigating such information-theoretic guidan... View full abstract»

    This paper briefly describes some of the characteristics, capabilities, and limitations of the bistatic radar when used for the detection and location of targets such as aircraft or satellites. (A bistatic radar is one in which the receiver is physically separated from the transmitter so that the echo signal does not travel over the same path as the transmitted signal.) Among the topics discussed ... View full abstract»

  • On Gyro Drift Models and Their Evaluation

    Random gyro drift, which is the uncorrectable drift that occurs in gyros, represents the major error input of inertial navigation systems that are required to operate over long time intervals. This random gyro drift must be taken into account whenever performing an error analysis or optimization study on such a system; otherwise, the results of the analysis or study would be meaningless. Random gy... View full abstract»

    Equipment to process and display beacon-derived altitude information is being developed to enhance the operational capability of the Air Traffic Control Radar Beacon System (ATCRBS). Beacon identity and altitude information assists the air traffic controller to establish positive identification quickly and reliably; radar handoff procedures are completed more efficiently. The principle altitude fu... View full abstract»

    The standard error deviation for the Doppler navigator is theoretically derived for the general case of both random and systematic errors. It is demonstrated that both the along-course error deviation and across-course error deviation, when expressed on a per unit basis, consist of two terms. One term is independent of the distance traveled and the other is dependent upon the distance traveled. Th... View full abstract»

    This paper is directed to the problem of transmitter-receiver leakage rejection in CW and FMCW radars which employ stepped-scanning antennas. An IF carrier-elimination filter has been devised and analyzed which provides leakage-rejection capabilities limited only by leakage variations during stationary beam positions. Leakage rejection is provided by coherently reducing the signal to zero IF, reje... View full abstract»

    Use of automatic height transmission, the essential "third dimension" for use in the control of aircraft, has been brought closer by action taken recently at the Seventh Session of the International Civil Aviation Organization. The Session recommended adoption of technical standards that will: 1) update and improve the existing international standards for SSR, better known in the U. S. as the Air ... View full abstract»

    This paper describes several methods of phase modulation radar in which the Doppler effect provides a carrier for range information. It is shown that these methods yield simple radar systems capable of measuring both the range and the speed of a target down to essentially zero distance. In contrast to conventional radars, only a nominal transmission bandwidth is required even under conditions wher... View full abstract»

    The airline industry, continuing its support for the development and implementation of the ATC radar beacon system, now strongly endorses the use of automatic altitude reporting. In discussing the pitfalls which have delayed implementation of the basic ATC radar beacon system, this paper calls attention to the need for automatic altitude reporting in the ATC system, and the need to provide it quic...

    The development of an unambiguous unit-distance code configuration for automatic altitude reporting via the ATC Radar Beacon System is described. This code provides for compatible altitude reporting in increments of 100, 250, and 500 feet within one common system. The code is developed by using Karnaugh mapping techniques. Some assumptions and requirements are set forth to provide guidance for the... View full abstract»

    This paper describes a radar system in which a measure of range is obtained as the phase difference between amplitude modulations on the transmitter and echo signals. Significant features of this AM radar system are simplicity and capability of accurately measuring very short ranges. For instance, an experimental unit ranges from zero to 50 feet with maximum error of six inches. View full abstract»
