针对无线电波透视仪发射机防爆不易实现的问题,提出使用周期矩形波代替单一正弦波作为发射波源的观点,通过对不同参数的周期矩形波进行频谱分析,选定参数优化后的周期矩形波与单一频率正弦波在实验室中实现了两种波源发射电磁波信号,用PR100宽带接收机接收的方案对比,证明了周期矩形波的优势。这种发射方式将克服原来仪器中不同频率需要不同谐振电路的缺点,大幅度减少使用电感电容的数量,对实现仪器防爆具有重大意义。
Aiming at the problem that the radiowave transmitter is not easy to be realized, the idea of using periodic rectangular waves instead of a single sine wave as the transmitting source is proposed. By analyzing the spectrum of periodic rectangular waves with different parameters, Single-frequency sine wave in the laboratory to achieve two kinds of wave sources to transmit electromagnetic signals, using PR100 broadband receiver to receive the program contrast to prove the advantages of periodic rectangular wave. This launch mode will overcome the original equipment different frequencies need different resonant circuit shortcomings, a substantial reduction in the number of inductive capacitors, to achieve instrument explosion-proof is of great significance.
