Abstract This work investigates a switchable 4G/5G dual‐antenna system designed for laptops. The dual open‐slot antenna structure is straightforward, with a slot width of only 2 mm. Each individual antenna features two different feed sections loc

Linear frequency modulation (LFM) waveforms have high Doppler-shift endurance because of the relative wide modulation bandwidth to the Doppler variation. The Doppler shift of the moving objects, nevertheless, constantly introduces obscure detection r

In this research, we present a novel method to prpocess extended targets with the combination of eigenwaveform and pulse compression. Three different target versions of spinning, un-spinning, and complex are included and analyzed with their return en

Linear Frequency Modulation (LFM) waveforms have high Doppler-shift endurance due to the relative wide modulation bandwidth. However, for Pulse-Doppler radars, the Doppler frequency shift from a nonstationary target causes range offset for matched fi

In this paper, we propose an integrated scheme to identify an extended moving target while trying to correctly locate its peak range-Doppler cell. The scheme is extended to handle multiple target responses. The cognitive radar platform uses adaptive

We propose an improvement to the maximum a posteriori probability weighted eigenwaveform (MAP-PWE) adaptive waveform design used in target recognition with a cognitive radar platform for which we call match-filtered PWE (MF-PWE). Our interest however
