title = "Intermodulation Radar with Dynamic Fundamental Tone Cancellation for Linearity Improvement",
abstract = "Intermodulation radar takes advantage of device nonlinear behavior for enhanced target detection. By selectively down-converting intermodulation tones at the radar receiver, it can distinguish nonlinear targets from linear background. One challenge of designing intermodulation radars is the linearity of the transceiver. The linearity of the receiver is critical for effectively suppressing the potentially stronger fundamental tones received by the receiver. In this paper, an intermodulation radar receiver with dynamic fundamental tone cancellation is proposed to relax the linearity requirement for the receiver. The impact of the phase and amplitude mismatch between the cancellation tones and the received tones is studied to understand specifications and performance limits of the proposed architecture.",
