An adaptive time delay of arrival (TDOA) technique has been implemented to automatically determine the proper time alignment of EMP response data acquired using delayed digitizers. Added benefits of the procedure are the quantitative assessment of data quality and proper signal conditioning for subsequent processing. This paper describes the procedures used for time tying transient responses, develops simple data quality models based on the structure of the cross correlation and demonstrates these models using test data. A procedure for conditioning a properly recon structed test data set is presented.

The paper describes an investigation to determine statistical variations for RFI demodulation responses in operational amplifier (op amp) circuits. AmplitudeModulated (AM) RF signals were injected into the op amp signal input terminals to produce undesired demodu lated responses at the 1 kHz AM-frequency. The RF frequency was varied over the range 0.1 to 400 MHz. First, 30 to 35 741 op amps were tested in an invert ing amplifier circuit with 10 kfl input resistor and 100 kfl feedback resistor (voltage gain A^ = -10) with out and with RFI suppression capacitors (27 pF). Mean values and standard deviations were determined for the demodulation RFI which was characterized by a nonlinear transfer function H2. When the RFI suppression capa citors were included, the experimental mean values for H2 were suppressed from 10 to 35 dB over the RF fre quency range 0.1 to 150 MHz except at 0.15 MHz where only 3.5 dB suppression was observed. Next, experi mental and NCAP computer simulation results are com pared for a 3-stage op amp circuit without and with RFI suppression capacitors. Macromodels were used for the 741 op amps in the NCAP simulations. Finally, the first op amp stage input resistor and feedback resistor were increased by a factor of ten. Four op amp types were inserted in the first stage. The op amps investigated were the 741 bipolar op amp (npn input transistors), the LM10 bipolar op amp (pnp input transistors), the LF355 JFET-bipolar op amp (JFET input transistors), and the CA081 MOS-bipolar op amp (MOSFET input transistors). Approximately 30 of each type were tested. Mean values and standard deviations were measured for demodulation RFI. At RF frequencies below 1 MHz, the CA081 op amp mean demodulation RFI response was 20 to 40 dB less than that of the other op amps. Beginning at 1 MHz, the LF355 op amp mean demodulation RFI response decreased rapidly with in creasing RF frequency and above 3 MHz was less than that of the CA081 op amp. From 3 to 200 MHz CA081 and LF355 mean demodulation RFI ‘responses were 20 to 30 dB less than that of the 741 op amp. The LM10 op amp mean demodulation RFI response decreased slowly from 3 MHz where it was the same as the 741 op amp to 200 MHz where it was between that of the CA081 and LF355 op amps.

A comparison is made of the three techniques for evaluating the vector potential arising in the pro blem of a vertical current element radiating over a lossy half-space: 1) the exact Sommerfeld integration, 2) the reflection coefficient method (RCM) ,and 3) the high contrast approximation (HCA) .The advantage of both approximate techniques, RCM and HCA, is that they circumvent the need for computing the Sommerfeld inte gral. The results of the analysis indicate that HCA yields acceptable results when the significant distan ce of the problem (the distance between the image and the field points ) is extremely small, i.e. in the sit uation when the RCM fails. It is concluded that the RCM and HCA complement each other over a relatively wide range of parameters of practical interest.

The objective of CS02 test of MILSTD-461/462 is to determine test sample's suscepti bility to the unwanted RF signals injected into its power leads. The test assures that the equip ment will not malfunction or degrade in performance when signals below a specified level are coupled into it through its power leads. Yet there seems to be some doubts as to whether the test method re commended will provide repeatable results and mean ingful data for predicting test sample's suscepti bility in a system. The paper describes how this discrepancy occurs and suggests remedial actions against it.

The electromagnetic compatibility (EMC) of electri cal and electronic equipment that are located in the below-decks areas of Naval ships is greatly deter mined by the emission and susceptibility character istics of their cables and the method in which these cables are run. The concern for protection against a nuclear electromagnetic pulse (EMP) and the desire to reduce the tremendous weight of shipboard cables has led to the development of the advanced marine cable (AMC). This cable is also referred to as the lightweight cable due to its thinner insulation and its single optimized braided [1] shield. Since a handbook [2] has already been developed to ensure the magnetic field compatibility of all below-deck cable installations, it became necessary to theoretically verify the electromagnetic inter ference (EMI) characteristics of these new cables. The incorporation of these cables into the handbook would facilitate their usage without compromising shipboard EMC. Utilizing cable data for the 233 cables, which was provided by one AMC cable manufacturer, the cables pitch diameter, pitch distance (lay length), and effective loop area (ELA) were calculated. Eight samples of various AMC cables were then tested utilizing a Helmholtz coil and a narrowband spectrum analyzer to determine their magnetic field suscept ibility. A comparison was made with a selected number of MIL-C-915 cables to illustrate that, although the AMC cable typically has a reduced magnetic field susceptibility (due to its typically smaller ELA), its variable lay technique, designed to reduce high frequency crosstalk on many AMC cables, can actually make them more susceptible to low-frequency magnetic field pickup.

Abstract A lumped, equivalent circuit of a transmis sion line is developed. The model uses a particular series expansion of the trigonometric functions involved in a solution of the transmission line equa tions and is suitable for use in computer-aided design codes. As opposed to many of the usual lumped circuit models, it appears that one can predict, independent of loading, the frequency range over which the model pro vides accurate predictions. The model also requires less topological complexity than the conventional methods. Comparisons to the predictions of the transmission-line model are given.
