    An overview of systems applications is presented to show the need for critical assessments of the performances required for the intended roles under the anticipated signal environments. System features are outlined to demonstrate that there is no single system concept to satisfy all roles. Current techniques and future goals are discussed to draw attention to the need for innovation in microwave d... View full abstract»

    The paper addresses the importance to naval operations of ESM systems features, including signal detection sensitivity, frequency measurement, angular accuracy and the essential capability to recognise specific emitters when their signals are immersed in a dense background of pulses from other sources. The challenging problems facing the designers of future equipment capable of satisfying this exp... View full abstract»

  • Intercept time and its prediction

    Intercept time is a key factor in the performance of electronic warfare (EW) surveillance and reconnaissance equipments. Interception relates to the probability of time coincidence of two or more parametric windows; scanning antennas, sweeping or stepping receivers and frequency-agile emitters give examples of such windows, where alignment or coincidence is required before detection can occur. For... View full abstract»

  • ESM range advantage

    Publication Year: 1985, Page(s):223 - 225
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (302 KB)

    Except in simple cases, the detection range advantage that an ESM intercept receiver achieves over a specified radar is difficult to quantify, owing to uncertainties of propagation and platform echoing characteristics. In the paper a parallel concept of ESM sensitivity advantage is developed which, together with a statistical description of radar cross-section, provides a simple but reliable estim...

  • Signal sorting in ESM systems

    As radar signal environments become denser and radar signals become more complex, the task of an ESM operator becomes more difficult. In environments where the numbers of radars may be large and the number of pulses transmitted by a radar may be small, the operator becomes the dominating factor in the efficiency of an ESM system. The paper discusses the problem of developing automatic sorting of r... View full abstract»

    The paper describes the use of metric techniques in an electronic support measures (ESM) data processing scheme developed at Smith Associates Consulting System Engineers Limited for the UK Ministry of Defence (Procurement Executive). The ESM data processing scheme takes in digital pulse data describing the radar pulses illuminating an ESM receiver. The output from the scheme is a continuously upda... View full abstract»

  • Sensitivity of crystal video receivers

    Publication Year: 1985, Page(s):233 - 244
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1240 KB)

    Tangential sensitivity is shown to be an inadequate criterion for comparing the operational performance of wideband crystal video ESM receivers. By contrast, it is shown that `receiver sensitivity¿¿ is completely described by a criterion that specifies a required signal detection probability for a give false-alarm rate. In particular, this alternative criterion is necessary for the correct design ... View full abstract»

  • Spiral antennas for ESM

    Cited by:  Papers (8)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (877 KB)

    The reason for the popularity of the cavity-backed spiral antenna in ESM systems is discussed, together with the surprising lack of supporting analysis and detailed understanding of its operation. In the absence of any published mathematical analysis of the complete antenna, the function and principle of operation of the three main antenna components¿¿the spiral radiator, backing cavity and balun ...

  • Antenna systems for ESM applications¿a land-mobile example

    Publication Year: 1985, Page(s):252 - 256
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (689 KB)

    The design of antenna systems for ESM applications requires that a number of demanding requirements be met simultaneously, each of them imposing constraints on the possible solutions that may be adopted. The paper uses the design of a land-mobile system employing a quad-ridged horn to illustrate briefly the various constraints and the solutions that can be adopted, indicating how the requirements ...

    Multi-octave contiguous channel multiplexers are a key component in EW systems, since they provide the front-end signal sorting. The paper describes advances in the development of broadband, low-loss, selective, lowpass, highpass and bandpass filters and contiguous channel multiplexers from 500 MHz to 26.5 GHz, in the form of suspended substrate stripline (SSS) realisations in particular to increa...

    IFM receivers using delay line discriminators for frequency measurement exhibit good performance characteristics in a pulsed signal environment. However, performance degrades for degrades for time-overlapped or complex signals. The paper presents an analysis with experimental verification for signal types such as pulsed, CW, linear FM and phase coded signals. More details are given for the case of... View full abstract»

    The paper deals with the application and operational requirements of tactical direction-finding equipment. An outline of the EW scenario in modern warfare is presented, concentrating on the direction-finding and position-fixing aspects. The need for a high order of accuracy is discussed, and it is suggested that this can only be achieved by means of wide aperture systems. The design requirements f... View full abstract»

    The simulation of systems using software models is a widely used technique for the reduction of design risk. This technique provides a means by which system performance characteristics may be predicted and investigated before major design and financial commitments are made.
