Frequency diverse array with random logarithmically increasing frequency offset

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...

Frequency-offset estimation for HIPERLAN

Frequency-offset correction is considered for a HIPERLAN (HIgh-PErformance Radio LAN) system over the indoor radio channel. Since the multipath channel response is not known a priori, a viable frequency-offset estimator should not depend on such knowledge. Such an estimator, using a single sample per symbol, is derived for HIPERLAN. The estimator is shown to approach the Cramer–Rao bound for fr...
