Abstract

Frequency diverse array (FDA) adds a tiny frequency offset which is much smaller than the carrier frequency between the signals transmitted by each antenna element. This introduces an additional degree of freedom in range dimension, resulting in a range-angle dependent beam pattern. Furthermore, the array's beam can be directed to different ranges at the same pointing angle. Multiple input multiple output (MIMO) radar transmits multiple orthogonal signals from the transmitter, and at the receiver, the received signals are separated by matched filters, thereby forming a virtual aperture, allowing for high-precision detection with fewer sparse array elements. Frequency diverse multiple-input multiple-output radar applies FDA to MIMO radar, possessing the advantage of both types of radar. Based on the characteristics of FDA and MIMO radar, this paper designs orthogonal signals which have good orthogonality and pulse compression performance for FDAMIMO radar. Numerical simulations are conducted to demonstrate the target detection and anti-interference capabilities of FDA-MIMO radar, detailed experimental comparison is to be done in further research.
