The detection characteristics of phase-shift keyed radar signal (PSKS) with gradual phase change obeying the Barker law have been considered. Analytical expressions were obtained for the PSKS detection characteristics under conditions of different a priori data regarding the signal parameters on the basis of calculations. It was shown that the gradual phase change lead to insignificant deterioration of the probability of the PSKS correct detection as compared with the stepwise phase change. © 2012 Allerton Press, Inc.

This study examines the impact of an input band-pass filter on the reception of phase-shift keyed signals (PSKS) with gradual phase change against the background of noises. In the case under investigation PSKS are received by a correlation receiver during the radar detection of targets. Analytical expressions of the target detection characteristics were obtained for PSKS with random initial phase and the amplitude containing regular and fluctuating components. This study also examines the relationships of the detection characteristics as a function of the input filter band-pass and the interval duration of gradual phase change. © K.H.

There are considered algorithms of resolution of sequences of measurements of frequency-temporal signals parameters by their belong to separate radio radiation source with simultaneous estimation of group set of position line parameters, realizing the principles of sequential extraction of the most informative and contrast data fragments. Results of statistical simulations are represented. © Allerton Press, Inc., 2012.

Auniversal neural-network algorithm for calculating coordinates of a fixed radiation source in network spatially distributed radio monitoring systems despite the sensor cell's shape is considered. Comparative analysis of a neuron-network algorithm when it is compared to statistically optimal and combined algorithms during implementation of differential-range, range and angle methods of location finding is conducted. © 2012 Allerton Press, Inc.
