METHOD AND DEVICE FOR MEASURING THE HEIGHT CORNER PROPERTY SEARCH in the review of nonlinear radar

摘要

1. Method for measuring the height of the corner of the object search in the review nonlinear locators that search objects containing active radioelements, comprising analyzing the amplitude of echoes from the search objects after their processing on the basis of the correlation integral convolution, characterized in that the measurement of the elevation is carried out by selecting number of parallel channels corresponding to a lifting height of the search object, according to the maximum attenuation factor, which depends substantially on the lifting height of the search object, n by applying to the channels in the correlators of band pass filters, the characteristics of which correspond to the heights of lifting objects detected in accordance with the attenuation factor calculated for the selected height, followed by combining all of the maximum selection circuit channels, the output is determined by the channel number with the expected height poiska.2 lifting object . Measurement apparatus angular height in the review nonlinear locators comprising two channels, one corresponding to the transmission channel, with the conversion of the probing signal to generate a correlator support composed of series-connected first analog-to-digital converter (ADC) and the transducer probe signal, the other corresponding to the receiving channel, connected in series with the receiver, a bandpass filter distinguishing a second harmonic which arises when converting to the active elements of the object list a and overwhelming the fundamental frequency of the probing signal and the second ADC, wherein a set of bandpass filters at the output of the second ADC connected in series
