Correction Analysis of Frequency Diverse Array Radar About Time

Research on main‐lobe deceptive jamming against FDA‐MIMO radar

“…By using a tiny frequency offset across the array elements, FDA provides a time-range-angle-dependent beam pattern bringing the possibility of joint location and detection of range and angle parameters, which has promising broad potentials in electronic counter countermeasures (ECCMs). Furthermore, MIMO radar has received significant attention due to its various advantages over conventional radar system [11][12][13], such as enhanced detection performance, improved parameter identifiability and angular resolution, providing more degrees of freedom (DOF) and better spatial coverage [14]. By combining FDA and MIMO technology, FDA-MIMO system has the result of associating a waveform to each point range/angle of the space, with the possibility of recovering this information in the receiver after appropriate processing [15].…”

Range‐angle beamforming with frequency diverse array radar using irregular superposed multicarrier approach for target indication

“…A more focused range-angle transmit beampattern can be produced using our proposed scheme. To solve the time-varying problem introduced in, 30,31 multiple matched filters at receiver [32][33][34] are adopted. Note that the transmit beampattern considered in this paper stems from the equivalent transmit beamforming at receiver, 35,36 which is different from the original transmit beampattern at transmitter.…”

FDA-MIMO Beampattern Synthesis with an Analytical Method

“…FDA radar has great application value because of its ability of range-angle-dependent [4][5][6]. To improve its application value, the literature [7][8][9][10][11] studied the time-variant problem of FDA radar. The literature [11] considers the FDA-MIMO radar scheme proposed in [12,13], which form time-invariant beampattern.…”

“…And they did not consider the influence of time parameters. Considering the influence of time parameters [11], a method of increasing frequency combined with window function is proposed in [18]. It is still a numerical solution.…”

“…(1) Through phase modulation, the FDA-MIMO radar system we designed can form a spot beam at any position in space. Literature [11] activates the rangedependent property of FDA through the signal processing at the receiver, and the matched filtering at the receiver is related to the frequency offset of the transmitting array element. Opposed to it, this paper weights the transmitted signal so that all the parameters related to the frequency offset are designed at the transmitter.…”
