Various correlation-based receivers have been proposed in passive bistatic and active monostatic radar exploiting orthogonal frequency-division multiplexing communications signals, but too little has been dedicated to establishing their relations and advantages over each other. Accordingly, this article provides an analytical comparison of the common filters in such waveform sharing scenarios, along with a performance analysis regarding three criteria: computational complexity, signal-to…

Correlation-Based Radar Receivers with Pulse-Shaped OFDM Signals
This paper compares the performance of two correlation-based radar receivers and reveals the multicarrier pulse shape as a relevant degree of freedom in waveform co-design approaches (e.g., cognitive radar/communication systems).
OFDM Joint Radar-Communications under Phase Noise: From Mitigation to Exploitation
Simulation results indicate quick convergence of ISAA to the hybrid Cram´er- Rao bound (CRB), as well as its remarkable performance gains over state-of-the-art benchmarks, for both FROs and PLLs under various operating conditions, while showing that the detrimental effect of PN can be turned into an advantage for sensing.
Joint radar and communications with multicarrier chirp-based waveform
The results show that better signal detection performance than OFDM and DFT-s-OFDM can be achieved on channels with large Doppler frequency and it is shown how transmit sequences can be selected in order to achieve 0 dB peak-to-average-power-ratio (PAPR) of the waveform.
Limited Feedforward Waveform Design for OFDM Dual-Functional Radar-Communications
Simulation results show that the proposed JWCSO approach provides significant performance gains over the conventional feedforward-agnostic waveforms and achieves near-optimal radar-communications trade-off performance, reaching the boundary of the CRB-capacity region with only a limited feedforward information.

A Unifying Approach for Disturbance Cancellation and Target Detection in Passive Radar Using OFDM
This paper proposes to revisit the reciprocal filter-based correlator and to reinterpret it as a so-called Doppler channel detector (CHAD), which allows a direct rejection of the ZDC, unifying in one and the same step the main disturbance mitigation and the detector construction.
Clairvoyant Clutter Mitigation in a Symbol-Based OFDM Radar Receiver
Two rejection filters that assume known the clutter covariance matrix are proposed that aim at mitigating not only the clutter main peak but also its noise-like pedestal that leads to target masking issues.
Reciprocal-Filter-Based STAP for Passive Radar on Moving Platforms
An appropriate space-time adaptive processing scheme is proposed to cope with the Doppler spread clutter returns aiming at ground moving target indication applications and exploits the benefits of the reciprocal filtering strategy applied at a range compression stage together with a flexible displaced phase center antenna approach.

A method of low-Doppler clutter cancellation which exploits the structure of an OFDM illuminating signal, and extends it to cancel specific blocks of delay and Doppler shift is considered.
