Performance Prediction and Waveform Properties of Passive Coherent Location Radar Systems in the Tarakan Area

Passive Coherent Location (PCL) System Radar is a variant of bistatic radar that exploits its illuminator as a source of radar transmission. The many of radio frequency (RF) illuminators in an area such as Tarakan in the form of FM radio (Pro-2 RRI), Digital TV (TVRI), cellphone base-station (4G-LTE), Wi-Fi, and so on have the potential to act as PCL. It is known that PCL can be considered as a radar system considering its advantages such as low cost without an active transmitter, support for various target measurements, anti-detectable electronic counter measures (EMC), and so on. This paper will provide performance predictions and analyze the waveform properties for the PCL illuminator. Performance prediction as a means of demonstrating the detection of range coverage is useful for predicting the whereabouts of targets. While analysis of waveform properties provides resolution and ambiguity function of the range and Doppler as the principal parameters of the radar. The results show that Pro-2 RRI with FM transmission has the farthest range of up to 12 km for a maximum SNR of 15 dB, 4G-LTE transmission has the smallest range resolution of 1606.5 m. Meanwhile, the smallest Doppler resolution obtained by TVRI transmission is ±300 Hz.
