Test the Doppler Effects of Codes That Generated by Genetic Algorithm Using Ambiguity Function
Diyala Journal of Engineering Sciences, 2015 Using pulse compression at the receiver side of communication systems yields sidelobes around the mainlobe that permits the clutter to pass through it, and mask the desired signal.

IET Radar, Sonar &Navigation, Volume 16, Issue 7, Page 1116-1130, July 2022., 2022 Abstract In this paper, the waveform design for Rician target detection with multiple‐input‐multiple‐output radar is addressed. The relative entropy between the distributions of the observations under two hypotheses is employed as the design metric. Due to the difficulty of tackling the non‐convex waveform design problem, a novel algorithm based on ...

A Hybrid Approach Based on PSO and Hadamard Difference Sets for the Synthesis of Square Thinned Arrays [PDF]
, 2009 A hybrid approach for the synthesis of planar thinned antenna arrays is presented. The proposed solution exploits and combines the most attractive features of a particle swarm algorithm and those of a combinatorial method based on the noncyclic ...

Moving target detection and tracking with multiplatform radar network (MRN)
IET Radar, Sonar &Navigation, Volume 16, Issue 5, Page 815-824, May 2022., 2022 Abstract A multiplatform radar network (MRN) composed of multiple transmitting and receiving facilities is advantageous over monostatic radar in moving target detection (MTD) and tracking due to the diversity gain. Within the framework of the Internet of Battlefield Things (IoBT), the authors propose that the airborne platforms equipped with the ...

Unimodular multiple‐input‐multiple‐output radar wave‐form design with desired correlation properties
IET Radar, Sonar &Navigation, Volume 16, Issue 3, Page 412-425, March 2022., 2022 Abstract Unimodular waveforms with good correlation properties are desired for multiple‐input‐multiple‐output radar to achieve an increased transmitting/receiving virtual aperture. In this study, a new optimisation framework is introduced to design waveforms with good correlations.

Range sidelobe suppression for OFDM-integrated radar and communication signal
The Journal of Engineering, 2019 To improve the RadCom system of performing both data transmission and radar-sensing functions, here a waveform design method for orthogonal frequency division multiplexing (OFDM) signal is proposed to solve the problem of high range sidelobe level in ...

Cassiopeia A: dust factory revealed via submillimetre polarimetry [PDF]
, 2009 If Type-II supernovae - the evolutionary end points of short-lived, massive stars - produce a significant quantity of dust (>0.1 M_sun) then they can explain the rest-frame far-infrared emission seen in galaxies and quasars in the first Gyr of the ...
