Moving target detection in the cepstrum domain for passive coherent location (PCL) radar

Ji-chuan LI,Xiao-de LU,Hui ZHANG,Peng-cheng YANG,Yu LIU,Mao-sheng XIANG

Frontiers of Information Technology & Electronic Engineering 2015, Volume 16, Issue 9,   Pages 785-795 doi: 10.1631/FITEE.1500036

Abstract: A cepstrum moving target detection (CEPMTD) algorithm based on cepstrum techniques is proposed for passiveThe primary cepstrum techniques are of great success in recognizing the arrival times of static targetTo estimate the Doppler frequencies of moving targets, we divide the radar data into a large number ofslow time dimensions respectively, we can obtain the range information and Doppler information of the movingTheoretical analyses show that only the target’s peak can be coherently added.

array of two periodic leaky-wave antennas with sum and difference beam scanning for application in targetdetection and tracking Research Article

Mianfeng HUANG, Juhua LIU,liujh33@mail.sysu.edu.cn

Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 4,   Pages 567-581 doi: 10.1631/FITEE.2200473

Abstract: An array of two periodic leaky-wave s (LWAs) with scanning is proposed for application in . The array is composed of two periodic LWAs with different periods, in which each LWA generates a narrow beam through the =-1 space harmonic. Due to the two different periods for the two LWAs, two beams with two different directions can be realized, which can be combined into a sum beam when the array is fed in phase or into a difference beam when the array is fed 180° out of phase. The array integrated with 180° hybrid is designed, fabricated, and measured. Measurement results show that the sum beam can reach a gain up to 15.9 dBi and scan from -33.4° to 20.8°. In the scanning range, the direction of the null in the difference beam is consistent with the direction of the sum beam, with the lowest null depth of -40.8 dB. With the excellent performance, the provides an alternative solution with low complexity and low cost for .
