    The authors state that 2004 has seen a major change to the operation of IEE journals. The entire process of submitting, reviewing, and accepting papers for publication is now carried out online, through a software package called Manuscript Central. The new scheme was introduced in April 2004. The authors acknowledge the roles of various groups in the production of each issue of the IEE journals. T... View full abstract»

    The effects of platform rotation, and in particular antenna rotation, on the performance of space-time adaptive processing (STAP) in clutter limited, forward looking airborne radar applications are considered. It is shown that there are two principal mechanisms. One involves the change of shape of the clutter surface in angle-Doppler space as the antenna rotates. STAP appears much more resilient t...

  • Robust horizontal line-of-sight rate estimator for sea skimming anti-ship missile with two-axis gimballed seeker

    A robust horizontal LOS (line-of-sight) rate estimator for a sea skimming ASM (anti-ship missile) is proposed. Based on the homing geometry, a precise LOS rate dynamics model for a two-axis gimballed seeker is derived. A new LOS rate estimator is designed by applying a robust Kalman filter to the LOS rate dynamics model. The proposed filter takes account of roll coupling effects and seeker detecti...

  • Fuzzy-logic-based IMM algorithm for tracking a manoeuvring target

    The authors propose a new fuzzy-logic-based interacting multiple model (FIMM) algorithm for tracking a manoeuvring target. The unknown target acceleration is regarded as an additional process noise to the target model, and each sub-model is characterised by the variance of the overall process noise, which is obtained on the basis of each acceleration interval. Since it is hard to approximate this ... View full abstract»

  • Signal transmission in passive media

    Under rather general assumptions, and in a relatively simple and straightforward manner, it is shown that the characteristics of signals which travel through homogeneous, as well as inhomogeneous, passive media have the principal features usually associated with the phenomena of precursors, as generally follows from more elaborate studies. The simplicity of the present arguments permits analytic s... View full abstract»

  • Experimental performance of a phase-switched screen against modulated microwave signals

    Publication Year: 2005, Page(s):29 - 33

    Experimental results describing the performance of an active phase-switched screen (PSS) radar absorber operating against modulated microwave signals are presented. A planar PSS is illuminated by pulse modulated and FM modulated radar signals with a carrier frequency of 11 GHz. The measured frequency spectrum of the reflected signals from the PSS in both its active and passive states are presented... View full abstract»

    The paper provides an analysis of SAR target geolocation accuracy due to aircraft motion errors. It studies the nature of errors in INS and GPS navigation systems and relates them to achievable SAR geolocation accuracy. The nature of the INS errors was found using a computer simulation. The GPS error characteristics were acquired from a stationary P-code receiver. The results of the study show tha... View full abstract»

  • Automatic censoring CFAR detector based on ordered data variability for nonhomogeneous environments

    Publication Year: 2005, Page(s):43 - 51

    The authors propose an automatic censored cell averaging (ACCA) CFAR detector based on ordered data variability (ODV) for nonhomogeneous background environments. The ACCA-ODV detector selects dynamically, by doing successive hypothesis tests, a suitable set of ranked cells to estimate the unknown background level. The proposed detector does not require any prior information about the background en... View full abstract»
