Range-azimuth decouple beamforming for frequency diverse array with Costas-sequence modulated frequency offsets

Different from the phased-array using the same carrier frequency for each transmit element, the frequency diverse array (FDA) uses a small frequency offset across the array elements to produce range-angle-dependent transmit beampattern. FDA radar provides new application capabilities and potentials due to its range-dependent transmit array beampattern, but the FDA using linearly increasing freq...

Joint Range and Angle Estimation Based on Sub- Array Scheme with Frequency Diverse Array Radar

Frequency Diverse Array (FDA) has its unique advantage in realizing Low Probability of Intercept (LPI) technology for its beam pattern is related to the range, time and angle. In this paper, a sub-array scheme of range-angle joint estimation of a target for Frequency Diverse Array (FDA) radar is proposed. To solve the problem of distance and angle response coupling of basic ULA FDA radar, the e...

Modulation Index Estimation of Frequency and Phase Modulated Signals

Modulation index estimation is important in the demodulation and recognition of Angle Modulation (AM) signals which include Frequency Modulation (FM) and Phase Modulation (PM) signals. In this paper, we firstly analyzed the AM signals with baseband modulation types, such as monotone, PSK, FSK, in the time and frequency domains. Then, we established a unified mathematical representation for the ...
