In radar system a challenging task is to achieve a good range resolution with a shorter pulse which needs more peak power. High peak power makes the design of transceivers complex because the devices used to build transceivers are able to withstand with high peak power. In literature pulse compression method is widely used to minimize the problem of using high peak power signal. In this paper, the problem of generating a high peak power signal with shorter duration, which is used to detect only moving targets has been addressed by proposing a novel radar pulse compression method using Linear Frequency Modulation with improved range resolution with a basic construction of a pulse processor which is analogous to a standard matched filter, and is reformed to suit an application. Multiple code types and lengths needed are used due to the flexibility in the design which reduce an uncertainties affected by the use of high pulse repetition frequencies.
