WebStretch Processing. To perform stretch processing, first determine a reference range. In this example, the goal is to search targets around 6700 m away from the radar, in a 500-meter … WebAbstract: This paper describes an approach to high range resolution (HRR) by means of stretch processing by digital deramping. This approach offers advantages that are common for stretch processing, as a moderate data rate for signal processing in the presence of a high bandwidth waveform.

WebApr 26, 2024 · Stretch and Pitch effect (Waveform Editor only) The Time And Pitch > Stretch And Pitch effect lets you change the pitch of an audio signal, the tempo, or both. For example, you can use the effect to transpose a song to a higher key without changing the tempo, or you can use it to slow down a spoken passage without changing the pitch. Note: WebApr 27, 2024 · Abstract: Stretch processing is widely used as a means to pulse compress the echoes produced by wideband LFM waveforms at a lower sampling bandwidth while still preserving high range resolution. Here the final fast Fourier transform (FFT) stage is replaced by a compensation transform that permits the use of other chirp-like nonlinear … city of daly city planningWebFor stretch waveform processing, the first LO is similarly modulated but with an extended sweep time to cover the selected range swath and timed to coincide with the return signal from that swath. For chirp waveform processing, the first LO is unmodulated during the return signal processing time. city of farmers branch human resources

WebH = phased.StretchProcessor creates a stretch processor System object, H. The object performs stretch processing on data from a linear FM waveform. H = phased.StretchProcessor(Name,Value) creates a stretch processor object, H, with additional options specified by one or more Name,Value pair arguments. WebStretch Processing Reasons for Using Stretch Processing. The linear FM waveform is popular in radar systems because its large time-bandwidth product can provide good range resolution. However, the large bandwidth of this waveform makes digital matched filtering difficult because it requires expensive, high-quality analog-to-digital converters.

WebSystems, Volume AES-7, March 1971. Stretch wave forms can reduce intermediate frequency (IF) and sig nal processing bandwidths by transmitting waveforms of duration longer than the range swath collection time. Stretch radar systems typically require waveforms of 300 MHz bandwidth and 500 microsecond time dura

WebStretch processing of the proposed waveform creates complications not present in traditional applications. The delayed portions of the chirps will appear as interference WebStretch processing with the use of a wideband LFM transmit waveform is a commonly used technique, and its popularity is in large part due to the large time-bandwidth product that provides fine range resolution capabilities for applications that require it.

Webstrproc = getStretchProcessor (waveform) returns the stretch processor strproc for the waveform System object™. By default the processor is set up so the reference range corresponds to 1/4 of the maximum unambiguous range of a pulse. The range span corresponds to 1/10 of the distance traveled by the wave within the pulse width.
