| titleOfInvention | Broadband monopulse tracking radar system with parabolic antenna |
| abstract | The invention discloses a broadband monopulse tracking radar system with a parabolic antenna, belongs to the technical field of radar detection and tracking, and can obtain more accurate target distance and angle measurement results. The system specifically comprises: the transmitting subsystem generates a transmitting signal under the action of the radio frequency excitation signal and outputs the transmitting signal. And the antenna feed subsystem receives the target echo signal, performs coupling correction and outputs the target echo signal. The frequency integration subsystem generates a radio frequency excitation signal to the transmitting subsystem and a receiving local oscillator signal to the receiving subsystem under the control of the control information. The receiving subsystem obtains a target echo signal and a receiving local oscillator signal, performs down-conversion processing to intermediate frequency, and outputs the intermediate frequency to the signal processing subsystem. The signal processing subsystem carries out digital down-conversion on the target echo signal to a baseband, then carries out amplitude and phase compensation and digital sum-difference processing to obtain a sum channel signal, a pitch difference channel signal and a azimuth difference channel signal, and further obtains the distance and the angle of the target and inputs the distance and the angle to the display control subsystem for display. |
