Radar control module and using method thereof

Abstract

The invention discloses a radar control module and a using method thereof. The control module comprises an FPGA module and a modulation module. The FPGA module is used for converting one path of TTL level input signal into n paths of TTL level output signals; the modulation module receives n paths of TTL level output signals transmitted by the FPGA module and controls the output signal Vd throughthe signals; an amplification module receives an output signal Vd of the modulation module and controls power amplification through the signal; and the phase of the output signal Vd is controlled by controlling the time sequence of the input TTL level input signal, so that an amplified signal without overshoot and with symmetrical leading edge and trailing edge is obtained, the frequency spectrumbandwidth occupied when the radar works in a saturated state is reduced, and the frequency spectrum resources are saved.

Description

technical field [0001] The invention relates to the technical field of radar, in particular to a radar control module and a method for using the same. Background technique [0002] With the development of microwave technology, the spectrum bandwidth occupied by traditional radar is getting wider and wider, and the spectrum resources are becoming more and more tight. This requires the development of radar to higher frequencies. However, in reality, due to the development of power amplifier devices It is impossible for spectrum resources to develop to higher frequencies indefinitely. Terahertz microwave devices have appeared at this stage, but their low output power and high design difficulty have once again affected their large-scale application. [0003] At the current stage, except for a small number of radars such as communication radars, most radars use power amplifiers that use saturation amplification as the amplification method. Due to the characteristics of the power...

Problems solved by technology

The timing control will inevitably have an impact on the waveform. The patent does not disclose the control module, nor does it apply the timing control to the voltage of the modulated radar. At the same time, it does not solve the problem that the spectrum bandwidth occupied by the radar is too wide and wastes spectrum resources.
