    Experimental observations with coastal radars at 3 and 10 cm wavelengths have revealed patterns in the sea returns which are stationary with respect to the radar site. the patterns take the form of a family of curves which exhibit a linear dependence upon wavelength and is characteristic of interference fringes. the mechanism proposed in the paper is forward scatter over the sea surface and subseq...

    The equations for the frequency of a crystal oscillator, and the sensitivity of frequency to the circuit parameters are here extended to consider: (1) the effects of motional capacitance, tuning capacitance, circuit capacitors, and the active element impedance; and (2) the Z-type oscillator. A precise normalized frequency difference between the frequency of oscillation and the series resonant freq... View full abstract»

    Hot air drying suffers from two serious drawbacks. On the one hand it is very non-uniform even under well-controlled conditions, on the other, the rate falls of sharply towards the end of the drying period. Often the net result is a product which is unevenly dried at poor energy efficiecny. Radio-frequency power can remedy both of these shortcomings. The advantages of radio-frequency power in dryi...

  • Admittance of a dipole antenna driven by a two-wire line

    Publication Year: 1976, Page(s):121 - 128

    A new theoretical approach to the problem of the symmetric dipole antenna, driven by a two-wire line, is presented. The dipole and the line are treated as a unique boundary-value problem, and, as a consequence, a new, conveniently defined, apparent driving-point admittance is introduced. The analysis of the problem leads to a system of two integral equations with the dipole and line currents as un... View full abstract»

  • Design of a flexible phase reversal modulation correlator

    Publication Year: 1976, Page(s):129 - 139

    A digital correlator is described for use with intra-pulse phase reversal modulated signals. The length and content of the binary sequence used can be altered at will from the front panel which adds onsiderably to its flexibility. It is particularly suited to ionospheric sounding but can find application in many areas of finite sequence correlation, e.g. radar. The paper discusses the reasons lead... View full abstract»
