    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»

    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»

    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.

    This paper shows that, if the signal-to-noise power ratio (S/N) is found for any steady deviation ¿ of a parameter from its required value, then in a closed-loop linear servo system, the actual rms variation of the parameter from its required value due to noise cannot exceed the rms value: 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»

    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»

    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»
