The invention provides a vehicle-mounted full-band interferometer based on a DSP. The vehicle-mounted full-band interferometer based on the DSP. comprises a DSP chip, an arbitrary pulse generation circuit, a signal interference coupling circuit, a synthesis amplifier, a mixer, a filter and a radio frequency antenna. The DSP chip is connected with the input end of any pulse generation circuit. Theoutput end of the arbitrary pulse generation circuit is connected with the input end of the signal interference coupling circuit; the output end of the signal interference coupling circuit is connected with the first input end of the synthesis amplifier. The output end of the signal interference coupling circuit is connected with the input end of the frequency mixer; the DSP chip is further connected with the other input end of the frequency mixer, the output end of the frequency mixer is connected with the input end of the filter, the output end of the filter is connected with the second input end of the synthesis amplifier, and the output end of the synthesis amplifier is connected with a radio frequency antenna. The antenna is low in manufacturing cost, can provide full-band interference signals, and is good in interference effect.
Description
technical field [0001] The invention relates to the field of vehicle technology, in particular to a DSP-based vehicle full-band jammer. Background technique [0002] The vehicle-mounted frequency jammer is a device fixed on the vehicle body, which is used on the route of the VIP convoy, during the police roundup of criminals, during military patrols, when performing security and explosive removal tasks, etc. At present, the vehicle-mounted frequency jammers on the market have high manufacturing costs, low utilization rate of electromagnetic energy, poor interference effect, and only interfere with specific frequencies, and cannot interfere with wireless remote control signals of any frequency. Contents of the invention [0003] The aim of the present invention is to solve at least one of said technical drawbacks. [0004] For this reason, the object of the present invention is to propose a kind of vehicle-mounted full-band jammer based on DSP, and manufacturing cost is lo...
