We present the problem of moving target detection with multiple-input multiple-output (MIMO) radar in compound-Gaussian clutter. A new moving target detector based on the Wald criterion is devised according to the centralized processing scheme of MIMO radar system. Furthermore, the adaptive version of the proposed detector is investigated by in place of the exact covariance matrix with the fixed point...
We investigate the problem of a monostatic pulse-Doppler radar transceiver trying to detect targets, sparsely populated in the radar's unambiguous time-frequency region. Several past works employ compressed sensing (CS) algorithms to this type of problem, but either do not address sample rate reduction, impose constraints on the radar transmitter, propose CS recovery methods with prohibitive dictionary...
This paper describes passive radar observations using the ATSC digital television signal as an illuminator. The system has two unique attributes. First, it recovers the reference signal by remodulation of the surveillance channel, a process which permits a compact single-antenna receiver. Second, it is shown that keystone formatting of the cross-ambiguity data mitigates range walk of moving targets...
Radio frequency interference (RFI) usually makes a great impact on through-wall radar (TWR) using ultrawideband signal to achieve high range resolution. In this paper, a phase-coded stepped-frequency (PCSF) waveform is designed to improve the anti-RFI performance of TWR, based on the fact that the different initial phase of the transmitted signals will have no effect on the receiver response to the...
This paper discusses the Brillouin precursor formation pertaining to LFM and random noise waveforms propagating through the dispersive media of Triply distilled water represented by the Rocard-Powles-Debye (RPD) dielectric model and the experimental data for the wet loamy soil.
Previous research has shown communication waveforms have potential for passive and active radar applications. The potential of a signal is typically characterized using the ambiguity function. This paper seeks to summarize the frequency division duplex (FDD) long term evolution (LTE) downlink (DL) signal structure and illustrate its effect on the signal's self and cross ambiguity functions. In addition,...
A major source of false-alarms in various radar applications is due to sudden noise spikes that cover wide frequency bands. These transient signals have high amplitudes and occur at random time instants. This leads to erroneous detection decision. In this paper, we study the influence of amplitude limiting the noisy signal on reducing the received false alarms and enhancing the detection performance...
The dynamics of many physical systems (maneuvering aircraft, satellites, etc.) are most easily described using nonlinear continuous-time differential equations, to which a stochastic process noise is added to handle unknown perturbations. Often, the magnitude of the process noise in a system depends upon the state, rendering the noise non-additive. This paper presents a variant of the cubature Kalman...

Focal plane arrays (FPAs) find applications in dish-antenna based receivers having multiple wideband beams. Such beams have a plurality of off-axes directions from the main beam. Maximally-decimated multirate 3-D digital FIR frustum filterbank can be employed in an FPA receiver to reduce directional jamming/clutter and other interference, noise, mutual electromagnetic coupling effects, and out-of-system...
Antarctic ice shelves are the fringes of ice sheets, that stifle the ice flow into the ocean. Determining the presence of internal layers in these ice shelves is very important for accurate measurement of the ice shelf melt rate. This paper introduces a novel method to detect presence of an internal layer (if there is any) that is masked by high amplitude antenna direct coupling returns or near surface...
Motivated by dual use of OFDM signal format for communications and radar in ever-worsening Electromagnetic (EM) coexistence environments, this paper deals with transmit waveform design problem considering multiple design objectives. Spectral nulling is a typical way for friendly coexistence with narrow band systems. However, a Non-Contiguous Orthogonal Frequency-Division Multiplexing (NC-OFDM) waveform...
In some digital radar systems, the matched filter is followed by a mismatched filter. In order to achieve computational efficiency, both the matched and mismatched filters could be implemented as several cascaded stages. This is particularly the case when the radar code is compounded from two codes or more. This is also the case when mismatched filters, such as those using sidelobe inversion, are...
