WebIt uses varying chirp rates to deramp the signal in different subapertures to eliminate the focus range problem. The steps between subapertures are also varied according the deramping chirp rate. The non-negligible cubic phase is compensated in each subaperture. The performance of the algorithm is demonstrated by computer simulation. WebApr 21, 2024 · A resistive coupler samples the transmit signal used to feed the deramping mixers and to use it in system calibration procedures. The receive chain consists of a broadband LNA, deramping mixers, signal drivers and power limiters to avoid damaging the SDR. ... Generating the transmission signal in software has the benefit that the chirp ...

WebJan 1, 2013 · Conventional frequency focusing method cannot directly used in this case. In this paper, deramping technique is employed to realize the coarse focusing and reduce the azimuth bandwidth, thus spectrum folding is mitigated. ... wa is the range and azimuth envelopes, respectively. k r is the chirp rate, c is the constant light speed, is the ... WebTranslation of "deramping" in English. Infatti, un bersaglio complesso può essere visto come composto da tanti bersagli puntiformi elementari, ognuno dei quali produrrà come eco un segnale chirp più o meno ritardato, a cui corrisponderà, dopo l'operazione di deramping, una diversa frequenza. A complex target can be considered as composed … WebAbstract. Abstract: Wideband signals are widely used in radar, navigation, satellite communications and so on. The matched filtering or multi-subband method is generally adopted in the processing wideband signals. In this paper dechirp pulse compression processing technique is presented.
