“…The proposed code gives better auto-correlation response when compared with Kasami and Gold codes which are commonly used to reduce side lobes in radar target detection process and also applicable to static objects only. For moving object detection the Doppler tolerance of the proposed codes are compared with [13,14]. The proposed approach gives large clear windows when compared with the existing methods.…”

“…In the proposed approach odd parity (Step 1) is appended to the codes and the resultant codes are represented in table 2 Now considering step 2, tables 3 and 4 depicts all the three cases of this step. From figure 6 it has been observed that the side noise is either of amplitude 0.2 or less than 0.2, which is the standard value of noise lobe [13,14]. There exist almost clear windows from frequencies 2 KHz to 40 KHz.…”

“…These codes detect only the static objects. The authors of [13,14] presented two different techniques to improve the target detection. However both the techniques maximize the mathematical complexity and delay which reduces the efficiency of target detection and may not be optimum to detect fast moving targets.…”

Now-a-days, entire nations need securities against warfare equipment’s to save their nation, and improve the battle field surveillance. Radar, alone is the major equipment that fulfills these requirements. However the radar technology possesses certain challenges to detect targets when they are moving with high speed as static and slow moving targets can be easily detected. In this connection the research community tried to improve the radar technology to detect fast moving targets in presence of Doppler noise. In this paper various binary codes have been designed to minimize the noise peaks below the radar threshold limit, which creates multiple windows and gives precise information of the moving targets. These sequences also have good autocorrelation property to get higher range resolution and compression ratio. The validation of the paper is done by Matlab.

“…The novelty of this paper uses the Trellis code, in addition to this approach uses equal-weighted hex codes to generate the input sequence for the trellis code to enhance the target detection with respect to desired Doppler. This paper is the extended version of (1) in which extra work has been carried out to improve target detection. The added work has three folds i.e.…”

Objective: Model the digital codes to enhance the detection of desired target in Multi-object environment. Methods: This study presents an effective mathematical model using convolution code, Trellis Code, and Quadratic Residue Technique to increases the probability of moving target detection. Findings: The proposed digital codes are efficient in detecting and tracking battle-field targets, slow-moving targets (helicopters, fighter aircraft), and fast moving ICBM (Inter-Continental Ballistic Missile). Application: The proposed approach can be used in surveillance, defense, and monitoring the weather forecast. It also provides an opportunity for researchers to improve the methodology for fast-moving targets at desired Doppler frequency. Novelty: This approach improves the merit factor (MF) of the main lobe and also reduces the amplitude of the side spikes below the threshold limit by creating multiple clear windows at various Doppler ranges. To authenticate the proposed model, a comparison between the proposed model and the existing model is presented. The work has been validated using Mat-Lab.
