... Simulations have shown that it should be possible to exploit this discarded phase information to achieve additional processing gain [9]. That is, evidence suggests …Jun 8, 2022 · Abstract. This paper discusses the design and test of an intermodulation radar receiver and a nonlinear tag. To discriminate reflections at the fundamental and the third-order intermodulation frequencies, the receiver was designed to attenuate the fundamental reflections and amplify the lower 3rd-order tone generated by the nonlinear target. Dec 15, 2021 · This paper presents a new SIMO radar system based on a harmonic radar (HR) stepped frequency continuous wave (SFCW) architecture. Simple tags that can be electronically individually activated and deactivated via a DC control voltage were developed and combined to form an MO array field. This HR operates in the entire 2.45 GHz ISM band for transmitting the illumination signal and receives at ...

Moreover Radar ambiguity function (RAF) is also analysed and used for studying various performance parameters of both NLFM and LFM waveforms. Key Words: Linear frequency modulated waveform, non-linear frequency modulated waveform, radar ambiguity function. 1. INTRODUCTION In the radar literature, LFM is known to be easilyApr 1, 2015 · The state of the art in nonlinear radar is conveyed by presenting high-level system architecture, explaining the rationale behind design decisions pertaining to that architecture, and listing the ... Nonlinear radar exploits the difference in frequency between radar waves that illuminate and are reflected from electromagnetically nonlinear targets. Harmonic radar is a special type of nonlinear ...Nonlinear radar exploits the difference in frequency between radar waves that illuminate and are reflected from electromagnetically nonlinear targets. Harmonic radar is a special type of nonlinear radar that transmits one or multiple frequencies and listens for frequencies at or near their harmonics.

For the present implementation of ARL’s nonlinear radar, the transmit waveform is a chirp which sweeps one frequency at constant amplitude over an ultra-wide bandwidth (UWB).

An efficient and secure use of the electromagnetic spectrum by different telecommunications and radar systems represents, today, a focal research point, as the coexistence of different radio-frequency sources at the same time and in the same frequency band requires the solution of a non-trivial interference problem. Normally, this is addressed with diversity in frequency, space, time ...Harmonic radar is an exciting technology for the detection and ranging of nonlinear targets. The advantage of harmonic radar is that it can separate linear clutter from the harmonic target response.
