The joint radar and communications (JRC) waveform often has a high range sidelobe, which will degrade the target detection performance of an automotive JRC system. To solve this problem, complementary group (JRC-CWG) design method is proposed in paper by exploiting philosophy sequence. In JRC-CWG, traditional unimodular waveforms, such as binary phase shift keying (BPSK) waveform, are used to p...

Controlling the radar beam-pattern by optimizing transmit covariance matrix is a well-established approach for performance enhancement in multiple-input-multiple-output (MIMO) radars. In this paper, we investigate joint optimization of waveform and antenna position vector MIMO system to approximate given beam-pattern, as well minimize cross-correlation between probing signals at number target l...

Dual-functional radar-communication (DFRC) systems can simultaneously perform both radar and communication functionalities using the same hardware platform spectrum resource. In this paper, we consider multi-input multi-output (MIMO) DFRC focus on transmit beamforming designs to provide sensing multi-user communications. Unlike conventional block-level precoding techniques, propose use recently...

Two stochastic methods for locating global minimum and optimal design parameters of a rectifier power transformer, by Genetic Algorithm (GA) and Simulated Annealing (SA) are presented. A closed form expression for actual phase current waveform of the rectifier transformer is derived and a comparison is made with the approximate waveform normally considered for fixing the transformer rating. The...

This article considers three interrelated adversarial inference problems involving cognitive radars. We first discuss inverse tracking of the radar to estimate adversary's us based on radar's actions and calibrate sensing accuracy. Second, using revealed preference from microeconomics, we formulate a nonparametric test identify if is constrained utility maximizer with signal processing constrai...
