PROJECT TITLE :

Range Resolution Improvement of a 24 GHz ISM Band Pulse Radar—A Feasibility Study

ABSTRACT:

An approach to boost the vary resolution of a twenty four-GHz industrial, scientific, and medical (ISM) band pulse radar is presented for the automotive short-vary radars. The resolution of the range profile was improved by applying the regularized least squares method to a discrete baseband signal at the receiver. For a 24-GHz ISM band pulse radar adopting a regularized least sq. method, a triangular pulse was identified as the optimal pulse shape underneath the regulations and in terms of price effectiveness. To resolve multiple adjacent pulses with a continuing false alarm rate, MATLAB simulations primarily based on the least absolute shrinkage and choice operator (LASSO) algorithm were used to derive additional threshold values for output signals once the LASSO operation and the required signal-to-noise ratio (SNR). The simulated and measured values of the required SNR were 20.five and twenty one.one dB, respectively, for the 2-target detection with a vary resolution of thirty cm, at the detection and false alarm probabilities of 0.nine and 10-3, respectively.
