The paper presents a method of improving the technical parameters of radioluchevoy protection system using wavelet transform. Radioluchevye technical means of protection are among the most common perimeter. Describes the operational principle of radioluchevoy protection system. Applying wavelet transform in the processing of the chirp signal is increased signal/noise ratio. It is estimated residence time violator in the area of protection. The estimation of the parameters of the wavelet transform with respect to the actual parameters of a violator and the actual characteristics of the system. Analysis of the information parameters chirp-signal showed that the main parameter is the frequency deviation. An important feature is the use of two different approaches: software and hardware. It is shown that the implementation of the wavelet transform, use the FPGA. Runtime wavelet transform on the DSP is not satisfactory to obtain the result in real time.
