Pulse waveform and phase modulation of phase conjugate wave良一 岩瀬純 直井年晃 菊池孝一 水谷Ryoichi IwaseJun NaoiToshiaki KikuchiKoichi Mizutani
Phase modulation is used to reject ambiguous targets while frequency modulation is used to achieve the finest resolution. Convolution of the phase modulated and frequency modulated waveforms yields a waveform which has the fine resolution property of the frequency modulated signal and the ambiguous ...
(SampleRate*ChipWidth) is an integer value — the number of samples in a chip must be an integer. Default: 1e6 Code Phase code type Specify the phase code type used in phase modulation. Valid values are: 'Frank' 'P1' 'P2' 'Px' 'Zadoff-Chu' 'P3' 'P4' 'Barker' 'Maximum Length ...
1.In this paper, the modulation characteristics of a reflective type standing wave acousto optic modulator are analysed theoretically.从理论上对“驻波声光调制器”的调制特性进行了分析,提出了从器件的设计、加工上保证在器件的声光互作用介质内形成强的驻波声场,和增加声光互作用介质的长度,以及改进匹配网络等...
Furthermore, frequency and phase modulations of the synthesized waveforms are easily implemented with this novel signal synthesizer; the modulation information is simply added to the digital outputs prior to selectively coupling. Thus when the ordered digital output is converted to an analog signal, ...

Using the continuous phase modulation framework [92], which is commonly used in aeronautical telemetry [93], deep-space communications [94], and the Bluetooth wireless standard [95], a PCFM radar waveform implementation has been developed [46,47] that converts an arbitrary polyphase code [θ0...
Femtosecond pulses are generated by Kerr-lens mode locking, yielding 24 nJ pulses with a duration of 28 fs (full-width at half-maximum (FWHM)) at a repetition rate of approximately 23 MHz44. The output pulses undergo further spectral broadening via self-phase modulation (SPM) in a ...
In the stepped-frequency radar system,motion introduces additive high order phase terms,which results in distortion of range profile.The phase modulation effect is analyzed and a novel ISAR imaging method is proposed for uniformly accelerative target,which based on predesigned waveform and phase cancella...
