| 成果简介 | NOVELTY - Invention relates to radar and can be used in both conventional radar and nonlinear radar. In the disclosed method, probing is carried out; a scattered signal is supplied to the input of the receiver in the form of a series of N single-frequency narrow-band coherent radio pulses with the same initial phases. These radio pulses are converted in the receiver so that the filling frequency of the converted radio pulses varies from pulse to pulse, wherein the spectrum of the received signal is substantially expanded. During further processing, a summed signal is formed from N adjacent radio pulses with different frequencies, which, after passing through a matched filter, enables to obtain range resolution N times better than that of the initial single-frequency radio pulse at the input of the receiver. Since a matched filter is applied at the end of the received signal processing, the signal-to-noise ratio is simultaneously maximized. Novelty is that a method is proposed for processing a received scattered signal in the form of a series of N coherent simple radio pulses with the same initial phases, which enables to obtain a range resolution which is the same as when using broadband probing signals. USE - Radar. ADVANTAGE - High accuracy in determining range by increasing the number of processed narrow-band radio pulses of the signal N scattered from the target, that is, the time of optimum or quasi-optimum processing in the radar receiver. 1 cl, 2 dwg |
