Web14 iun. 2024 · Multi-carrier Agile Radar (WMAR), which transmits/receives wideband waveforms simultaneously with every antenna. To avoid the increased cost associated with wideband waveforms used by WMAR, we next propose multi-Carrier AgilE phaSed Array Radar (CAESAR). CAESAR uses narrowband monotone waveforms, thus reducing Webboth radar and communication, numerous researchers have studied the implementation of DFRC in recent years. For example, the authors in [3] use the frequency and spatial agility properties of the carrier agile phased array radar to implement a DFRC and achieved comparable communication performance to an independent device while guaranteeing
Non-Linear Signal Processing Methods for UAV Detections from a Multi …
WebModern radar systems are expected to operate reliably in congested environments. A candidate technology for meeting these demands is frequency agile radar (FAR), which randomly changes its carrier frequencies. FAR is known to improve the electronic counter-countermeasures (ECCM) performance while facilitating operation in congested setups. … WebThe fundamental principle of the phased array antenna is the phase-dependent superposition of two or more radiated signals. When the signals are in-phase, they combine together to form a signal of additive amplitude. When the signals are counter phase, they cancel each other. The three types of phased array antennas are 1) linear array, 2 ... tisとは it

Webdegradation in both radar and communication performance. In this work we propose a DFRC scheme based on the carrier agile phased array radar (CAESAR), which … WebHere, we propose two multi-carrier agile phased array radar schemes. The first uses all the antenna elements to transmit a single waveform consisting of multiple carriers … WebInspired by the excellent performance of recent frequency agile radar (FAR) technology in complex electromagnetic environments, we propose the multi-carrier agile phased array radar (MAPAR). MAPAR enhaces the performance of FAR by transmiting multiple carrier frequencies in a single pulse with separate sub-arrays of antennas for each frequency. tiszaroff fogorvos
