| Abstract: | In this paper the principle of PWPF (pulse-width pulse-frequency modulator) is introduced and its working performance is analyzed. To the requirement of variable thrust in terminal guidance of the interceptor, PWPF modulator is used to modulate the state of constant thrust motor to design "the digital variable thrust" required by the proportional navigation law to the light interceptor out of atmosphere with constant thrust orbit control motor. |
