FIELD: radio, communication.SUBSTANCE: signals are received by antenna array elements, their amplification in low noise amplifier, converting to digital form in the analogue-digital converter, as the external source of illumination the radiation of simultaneous several television channels is used, operating at different carrier frequencies, and in the electronic computer machine the joint parallel processing of signals on K carrier frequencies is carried out in the band of television broadcasting and the signal non-coherent accumulation, for which each element of the antenna array receives the signal which is a superposition on several carrier frequencies, the signals from the output of the antenna array elements, after amplification and prior to conversion to digital form, are divided into K signals using a divider and a set of band-pass filters, then the resulting output signal is obtained with an increased total capacity, which is compared to the threshold.EFFECT: increase in target detection range and reduction of probability of false alarms due to the use of joint processing of signals at several carrier frequencies.4 dwg |
