Normalized length of the receive antenna array: $ L_r =n_r \Delta_r $ $$ |cos\theta |=\frac{1}{n_r }\frac{|1-e^{-j2π∆_r n_r Ω_r } |}{|1-e^{-j2π∆_r Ω_r } |} =|\frac{sin(πn_r ∆_r Ω_r)}{n_r sin(π∆_r Ω_r)}|=|\frac{sin...
Mathematical Analysis of a Modified Closed-Form Formula for Design a Uniform Leaky-Wave Antenna With Ultra-Low SLLStraight long slots have high side-lobes in the far-field amplitude patterns, which reduces their use as high-performance antennas. To reduce these side-lobes, a long slot may be ...
intensity, and valence of external stimuli, so they can properly navigate their environment. However, constant ecological and internal state fluctuations threaten the animal’s ability to accurately represent these stimuli. To address the demands these fluctuations impose, sensory systems use processes ...

Similar to the antenna aperture in the spatial spectrum estimation theory [26], when the pulse number is fixed, the larger the stepped frequency, the greater the total frequency difference, and the higher the resolution of the range spectrum. We set three stepped frequencies: 0.5 kHz, 1 kHz,...
