Abstracting of the Message Feature of Frequency of Doppler Signal Received by Radio Proximity Fuze for Air-attack by Using Time-frequency Analysis Method
Zhang Fei · 2003
With the development of DSP technology and the advent of superior DSP, it is possible to abstract real time time Varing frequency of the signal. In this paper, two calculating frequency methods respectively by enumerating and time frequency analysis are analyzed and compared with each other in aspect of indicating time varing feature of signal's frequency. At last, the feature of Doppler frequency of signal received by the radio proximity fuze for air attack during projectile target engagement is demonstrated through simulation.
