in the following sections we will discuss the details of the spice model and the simulation parameters used in the simulation. the spice model is a comprehensive simulation model in which all the components of the radar receive system are represented and the model is verified for radar input and output signal. the radar hardware and the software are simulated in a single environment. the spice model consists of two components, namely the hardware and the software. the hardware is represented by the netlist, which gives a precise detail of the circuit design. the software is a simulation model that generates waveforms that can be compared with the waveforms received from the radar. the simulation model is also used to design the radar hardware and is based on the netlist.
it is to be noted that the modified spice model is capable of simulating cw and fm-cw radars. it is one of the most versatile and widely used simulation models in the area of radar and communication systems. furthermore, the spice model is capable of simulating the transmit and receive waveforms.
the radar data is gathered from the indian mst radar, which is operated at the narl, gadanki, andhra pradesh. this time-series data is subjected to the adp, which normally uses the method of periodogram for the calculation of power spectrum. the output snr estimated using adp and spice_gs for east and south beams are depicted in fig. 2.

the purpose of this paper is to investigate the physics of the plasma to determine the method of coupling the plasma to the electromagnetic field. the physics of the plasma is investigated by determining the coupling coefficient of the medium and the refractive index. the results of the study show that the plasma can be used to enhance the radiation of the electromagnetic field. the refractive index is determined by using the maxwell equations. the electric field is derived by applying the maxwell equations to the plasma. the method of calculation is explained in this paper. the coupling coefficient is obtained from the field generated by the plasma. the radiation characteristics of the plasma are obtained by calculating the electromagnetic field. the coupling coefficient is determined by using the equations for the electromagnetic field and for the plasma. the radiation characteristics of the electromagnetic field are obtained from the electric field. the electromagnetic field is calculated by using the maxwell equations, and the plasma is calculated by using the plasma equations.
the fast implementation of semiparametric method for spectrum estimation, i.e., spice_gs, is applied to mst radar data retrieved from the narl. since the gohbergsemencul factorization of the covariance matrices is applied, we can leverage the toeplitz/block-toeplitz structure to compute the spectral estimate. the processed results have revealed noteworthy computational reductions. a considerable increase in computational efficiency has been obtained by spice_gs, devoid of the loss in performance.
