Design and implementation of Pulse Generator Circuit for Marine Radar application

This research work focuses on design and implementation of pulse generator circuit for marine radar application. In this research, the pulse generator is designed for generating rectangular pulses having 200 µs pulse width of which rates arc 3200 pulse per second (pps) and 800 pulse per second (pps). This circuit is also designed for working in high power radio frequencies. Discrete devices are used extensively for ruggedness and robust system design. Since the stability of trigger generator is essential, performance rests were carried out by using multitestmeter, oscilloscope and frequency counter. Circuit simulation was done by using Circuit Maker version 2000 software. Experimental results are analyzed and compared with the theoretical findings and simulation results. The investigation shows that the results were found to be within the rated value of 3200 ± 32 Hz and 800 ± 8 Hz
