This paper presents a target direction finding using six-port technique for short range radar based sensor. Direction finding of the target is determined by performing phase measurement of the incident wave at the receiver side. This technique is also known as Direction of Arrival (DOA) detection method. In this paper, the operation of target direction finding is performed and simulated using Keysight...
This paper presents the development of the six-port baseband processing system for short range radar based sensor. Short range radar involved in many applications such as the used in the automotive system. The analog baseband circuit commercially exists nowadays, but it a little bit bulky and expensive. In this paper, the design of a RF power detector using microstrip technique is presented. The design...
A six-port demodulator in homodyne direct conversion receiver is presented in this paper. The direct-IF or zero-IF conversion process is performed by several circuit designs in the demodulator such as six-port correlator and proposed power detector circuit. They are able to produce baseband signals and constellation diagram of QPSK operation. Six-port correlator contains double-stage Wilkinson power...
